4:46 PM PT -- Ryan Shazier tells TMZ ... "Michelle and I have been living apart and are currently separated. As we work through what comes next for our family, I ask for privacy and prayers."

Ryan Shazier is a "liar and a cheater" ... this according to his wife, who just put the former NFL linebacker on blast by sharing raunchy text messages she claims he sent to another woman.

Michelle Shazier -- who has been with Ryan well before his career-ending spinal cord injury in 2017 -- unleashed on her husband in a since-deleted Instagram post on Wednesday ... saying, "A person that loves his family … this is what they do to their family … the WIFE.. that has been there for him since day 1!"

Michelle -- a former college basketball player who has raised two boys with the Pro Bowler -- posted multiple text exchanges allegedly between Ryan and a woman named Marie ... and while they initially start off as casual flirting, things eventually got more intense.

In fact, in one screenshot, a text exchange shows the person Michelle claims is Ryan sending links to books titled "The Ultimate Guide To Anal Sex For Women" and "Blow By Blow: A Step-by-Step Guide On How To Give Blow Jobs So Explosive That He Will Be Willing To Do Anything For You."

"Infidelity at its finest!" Michelle continued in her post. "I can’t sit here and keep hiding anymore . You can have it. I deserve better. 🤍 This is Ryan… he’s a liar and a cheater!"

Ryan and Michelle got married back in May 2019. He has yet to address the allegations.

Big news out of Big D ... Mark Cuban is selling his majority stake in the NBA's Dallas Mavericks, while still holding onto the reigns in basketball operations.

The billionaire is selling his majority stake to Miriam Adelson ... TMZ Sports has confirmed.

While Mark is selling a stake reportedly valued at $3.5 billion, he will retain some shares in the team and be the lead decision-maker when it comes to basketball ops.

Cuban bought the team in 2000 for $285 million, so he’s getting a huge return on investment!

Miriam is the billionaire widow and heiress of Sheldon Adelson and his Las Vegas casino empire ... Forbes has her net worth at $32.3 billion, making her the fifth richest woman in the world.

Our sources say Adelson has plans to build a new arena for the Mavs, and, if a gambling bill passes in Texas, we’re told she might also build a casino in Dallas.

Miriam is reportedly selling $2 billion of her shares in Las Vegas Sands Group to make the Mavs purchase.

Under Cuban, the Mavericks have been perennial contenders in the NBA's Western Conference, winning the franchise's first and only NBA championship in 2011, defeating LeBron James and the Miami Heat.

Earlier this week, Cuban revealed he's leaving ABC's "Shark Tank" after the upcoming 16th season.

Lots going on in Mark’s world … including cohosting “TMZ’s Merry Elfin’ Christmas” special, premiering Dec. 5 in primetime on Fox!

Grandes noticias de Big D... Mark Cuban está vendiendo su participación mayoritaria en los Dallas Mavericks de la NBA, aunque todavía se aferra a las operaciones de baloncesto.

El multimillonario está vendiendo su participación mayoritaria a Miriam Adelson, según ha confirmado TMZ Sports.

Aunque Mark está vendiendo su participación supuestamente valorada en $3,5 mil millones, conservará algunas acciones en el equipo y será el principal responsable de la toma de decisiones cuando se trate de las operaciones relacionadas al baloncesto.

Cuban compró el equipo en 2000 por 285 millones de dólares, ¡así que está obteniendo grandes ganancias de su inversión!

Miriam es la multimillonaria viuda de Sheldon Adelson y heredera de su imperio de casinos en Las Vegas. Según Forbes, su patrimonio neto asciende a 32.300 millones de dólares, lo que la convierte en la quinta mujer más rica del mundo.

Según nuestras fuentes, Adelson planea construir un nuevo estadio para los Mavs y, si se aprueba una ley sobre el juego en Texas, también podría construir un casino en Dallas.

Al parecer, Miriam está vendiendo 2.000 millones de dólares de sus acciones en Las Vegas Sands Group para realizar la compra de los Mavs.

Bajo Cuban, los Mavericks han sido contendientes perennes en la Conferencia Oeste de la NBA, ganando el primer y único campeonato de la NBA de la franquicia en 2011, derrotando a LeBron James y los Miami Heat.

A principios de esta semana, Cuban reveló que dejará "Shark Tank" de ABC después de la próxima temporada 16.

The people who allegedly supplied TikTok star Cooper Noriega with the illicit drugs that caused his fatal overdose have been arrested in connection with his death.

The feds say a California man who allegedly ran a drug trafficking operation providing same-day delivery of cocaine and fentanyl-laced pills has been arrested and arraigned on federal narcotics charges ... and he's accused of supplying the drugs in a fatal fentanyl overdose.

Prosecutors say the victim at the heart of the case is "C.N." and Cooper's dad says the victim is Cooper.

Prosecutors say Erick Oved Estrada ran an illegal drug operation out of his Calabasas home ... with one of his associates delivering fentanyl-laced oxycodone to C.N., which ultimately caused a fatal overdose.

TMZ broke the story ... back in June, Cooper was found dead in a mall parking lot outside Los Angeles. Subsequent reports revealed he died from an accidental drug overdose.

The feds say Estrada sold fentanyl-laced pills to Arian Alani ... and Alani sold them to C.N., who ingested them and died of an OD.

Prosecutors allege Alani texted Estrada, "my boy just died yesterday," in reference to C.N. ... and that Estrada "shouldn't be selling (expletive) with fentanyl."

The feds say Estrada and Alani are each charged with one count of distribution of fentanyl resulting in death, among other charges.

Las personas que presuntamente le suministraron las drogas ilícitas a la estrella de TikTok Cooper Noriega, que luego causaron su sobredosis fatal, han sido arrestadas.

Los federales dicen que un hombre de California que supuestamente dirigía una operación de tráfico de drogas y proporcionaba entregas de cocaína y píldoras de fentanilo el mismo día fue arrestado y procesado por cargos federales de narcóticos y está acusado de haberle suministrado las drogas que le causaron una sobredosis fatal de fentanilo.

Los fiscales dicen que la víctima en el centro del caso es "C.N.". El padre de Cooper dice que la víctima es Cooper.

Los fiscales dicen que Erick Oved Estrada tenía una operación ilegal de drogas afuera de su casa en Calabasas, y uno de sus socios fue el que le entregó oxicodona con fentanilo a C.N., que en última instancia causó una sobredosis.

TMZ fue el primero en informar la noticia, en junio, Cooper fue encontrado sin vida en un estacionamiento de un centro comercial afuera de Los Ángeles. Los informes posteriores revelaron que murió de una sobredosis accidental de drogas.

Los federales dicen que Estrada le vendió píldoras con fentanilo a Arian Alani, y este se las vendió a C.N., quien las ingirió y murió de una sobredosis.

Los fiscales alegan que Alani envió un mensaje de texto a Estrada diciendo, "mi chico acaba de morir ayer", en referencia a C.N. y que Estrada "no debería estar vendiendo (improperios) con fentanilo".

Los federales dicen que Estrada y Alani están acusados cada uno de un cargo de distribución de fentanilo con resultado de muerte, entre otros cargos.

Michael Chiarello, a celebrity chef, died from an allergic reaction that set off a fatal chain of events ... this according to the coroner.

The former "Food Network" star's official cause of death is an allergic reaction resulting in anaphylactic shock, leading to a heart attack ... the coroner in Napa County tells TMZ.

We're told Michael's allergic reaction sent him to a hospital, where he was brought back to life only to later die of hypoxic-ischemic encephalopathy -- a brain dysfunction caused by a lack of oxygen and blood flow.

The coroner also tells us recent cocaine use was another "significant condition" noted in the final findings on Chiarello's death ... but we're told although cocaine was in his system, he did NOT die from a drug overdose.

As we reported ... Michael died Oct. 7 at Queen of the Valley Medical Center in Napa, where he was hospitalized due to an allergic reaction.

It's still unclear if Michael's fatal allergic reaction was food-related, or what it stemmed from.

Michael had a long run on TV, with his show "Easy Entertaining With Michael Chiarello" airing for 10 seasons on Food Network.

The star chef was also featured on hit series like "Chopped," "The Next Iron Chef" and "Top Chef."

Michael Chiarello, un connotado chef de celebridades, murió de una reacción alérgica que desencadenó una cadena fatal de eventos, según explica el forense.

La causa oficial de muerte de la ex estrella de "Food Network" fue una reacción alérgica que resultó en un shock anafiláctico, lo que le produjo un ataque al corazón, dice el médico forense del condado de Napa a TMZ.

Nos dicen que Michael fue llevado a un hospital tras la reacción alérgica, donde lograron revivirlo solo para morir más tarde de encefalopatía hipóxico-isquémica, una disfunción cerebral causada por la falta de oxígeno y flujo sanguíneo.

El forense también dice que el consumo reciente de cocaína fue otra "condición significativa" de la que repararon en las conclusiones finales sobre la muerte de Chiarello. Pero nos dicen que aunque la cocaína estaba en su sistema, no murió de una sobredosis de drogas.

Como hemos informado, Michael murió el 7 de octubre en el Queen of the Valley Medical Center en Napa, donde fue hospitalizado debido a una reacción alérgica.

Todavía no está claro si la reacción alérgica que produjo la muerte de Michael estaba relacionada con la comida o lo que se derivó de ella.

Michael tuvo una larga carrera en televisión, con su programa "Easy Entertaining With Michael Chiarello" emitido durante 10 temporadas en Food Network.

El chef estrella también participó en exitosas series como "Chopped", "The Next Iron Chef" y "Top Chef".

Tyga set out to make his 34th birthday legendary and based on this evidence, he succeeded ... twice, with parties in Vegas and Los Angeles this week surrounded by plenty of his celebrity pals!!!

Tyga's first string of celebrations kicked off inside Vegas' Spearmint Rhino strip club immediately after the F1 racing events, in the early hours of Nov. 19 ... and we're told everybody and their momma showed up.

YG, Saweetie, Swae Lee, Future, French Montana, Coi Leray, Odell Beckham Jr., Nav and Russell Westbrook were all Last Kings and Queens that evening!!!

Tyga's longtime bud Lil Wayne didn't want him to shoulder the load alone having to dole out stacks of cash to the strippers in the venue, and made a very supportive appearance ... his and Fat Joe's classic "Make It Rain" anthem clearly still lives up to that title!!!

Sunday was T-Raww's actual birthday and he enlisted the WTB Agency to morph a private West Hollywood residence into a makeshift club "Studio 34" ... disco ball and all!!!

The 2nd shindig was highlighted by cameos from Leo DiCaprio, Chris Brown, Kaytranada,  and Bryson Tiller ... and Saweetie, DDG and 310Babii all grabbed the mic for live performances!!!

Britney Spears' bizarre social media post about her shirtless "uncle" isn't actually one of her actual relatives ... but the guy in the pic is super close to the singer, and we know who he is.

Here's the deal ... Britney posted a strange photo on Instagram Tuesday night of a shirtless man taking a mirror selfie, which she captioned ... "This is my uncle 😉 !!! What if his back is my face 🤔🤔 ???"

Britney fans were left wondering who the hell the "uncle" is -- his face is out of the frame -- and what the hell Britney was talking about.

Sources with direct knowledge tell TMZ ... the guy in Britney's post isn't her uncle, it's her longtime manager and best friend Cade Hudson.

We're told Britney posted an old photo of Cade from a few years ago, and there's no real meaning behind her post ... basically, she was just being silly and having fun with her followers.

For the record, here's Britney's real uncle, Willie Spears ... who bears no resemblance to Cade.

El extraño "tío" sin camiseta que Britney Spears subió a sus redes sociales no es en realidad un pariente real, pero sí es súper cercano a ella y sabemos quién es.

La cuestión es así, Britney publicó una extraña foto en Instagram el martes por la noche en donde aparece un hombre sin camiseta tomándose un selfie en el espejo. Como comentario, escribió: ¡¡¡"Este es mi tío 😉 !!! Qué tal si su espalda es mi cara 🤔🤔 ???".

Los fans de Britney se quedaron preguntando quién demonios era el "tío" y a qué se refería Brit con todo esto. Su cara está fuera del encuadre, por lo que no se puede ver.

Fuentes con conocimiento directo le dicen a TMZ que el hombre en el post no es su tío, es su manager de toda la vida y mejor amigo Cade Hudson.

Nos dicen que Britney publicó una foto de Cade de hace unos años y que no hay ningún significado real detrás de su post. Básicamente, estaba tomándole el pelo a sus seguidores.

Para que conste, así luce el verdadero tío de Britney, Willie Spears, que como pueden ver no tiene ningún parecido con Cade.

Todd Chrisley won't be celebrating the coming weeks as the most wonderful time of the year ... he's disgruntled about not being able to spend the holidays with his family while locked up.

Todd's attorney, Jay Surgent, tells TMZ ... Todd's very upset about his situation as his first holiday season behind bars begins and he's around other inmates instead of loved ones.

We're told Todd's daughter, Savannah, is planning to visit both Todd and Julie in prison at some point over the holidays ... but it obviously won't be their normal holiday routine.

Remember, Julie's locked up too ... with the Chrisleys sentenced to hard time after being convicted last year in their bank fraud and tax evasion trial.

Savannah, of course, wants her parents home for the holidays ... but it's not happening for a while, even though Todd and Julie have been able to get their 12 and 7-year sentences reduced -- Todd got 2 years off, and Julie got 1 off.

Todd's going to be served a special Thanksgiving spread at FPC Pensacola in Florida ... but it's a far cry from the home cooking he's used to.

While it sounds like reality is starting to sink in, Todd's attorney tells us they are still exploring legal strategies for how to get him home early ... Surgent says Todd has a new court date in March where his legal team will try to reverse his conviction.

Suzanne Shepherd, who had key roles in "The Sopranos" and "Goodfellas," has passed away ... according to her family.

Suzanne's daughter, Kate Shepherd, tells TMZ ... her mother passed away in her sleep Friday morning. She says cause of death has not been determined yet, but she says Suzanne was suffering from chronic obstructive pulmonary disease ... and she had grown much weaker in recent days.

Suzanne appeared in 20 episodes of "The Sopranos" as Mary DeAngelis ... the mother of Edie Falco's character Carmela Soprano. She had a similar role in the classic, "Goodfellas" ... playing mother to Lorraine Bracco's Karen Hill.

Suzanne was also in other hit films, like "Uncle Buck," "Requiem for a Dream," "Working Girl" and "Mystic Pizza" ... and she was also on the CBS TV series, "Blue Bloods."

Aside from her impressive acting career, Suzanne was a beloved acting coach and also directed regional theater productions around the world.

She is survived by Kate, son-in-law Miles, daughter-in-law Joyce and granddaughter Isabelle.

Suzanne was 89.

Harry Styles ha cambiado su sexy melena por una cabeza rapada. Al menos eso fue lo que vimos mientras disfrutaba del último concierto de U2 en Las Vegas con su novia, Taylor Russell.

El cantante acudió al Sphere en Las Vegas la semana pasada con su nuevo peinado mientras disfrutaba con Taylor de algunos de los éxitos de U2 con su brazo alrededor de ella. Si todavía no estás seguro de que son pareja, ¿qué más pruebas necesitas?

Los testigos nos dicen que estuvieron abrazados toda la noche. Además de darse un montón de besos y tomarse muchas selfies mientras U2 rockeaba.

Eran parte de un grupo numeroso y todo el mundo lo estaba pasando en grande, incluso bailaron en un círculo hacia el final de la noche.

El corte de pelo puede ser un poco chocante para los fans de Harry, si usted está acostumbrado a la era de One Direction o su exitosa carrera en solitario, una cosa que siempre gustó era su pelo largo y frondoso.

Como informamos, Taylor y Harry han sido vinculados desde julio, cuando ella recibió un pase VIP para su concierto de Viena. Han sido vistos juntos desde entonces y han compartido algunos momentos románticos en público la noche de prensa de su obra de teatro en Londres llamada "The Effect".

DJ Jazzy Jeff and The Fresh Prince reunited on stage for the first time in years last night in L.A. for the Grammys ... a full-circle moment for the legendary pair!!!

The dynamic duo performed a rendition of hits -- "Brand New Funk," "Gettin' Jiggy Wit It," and "Summertime" -- inside YouTube Theater in Inglewood as part of the Questlove-co-produced "Grammy Salute to 50 Years of Hip-Hop" special.

Will was reportedly taping "Bad Boys 4" when Quest tried to get him for the Grammys' celebration of hip hop's milestone birthday during the award show back in February -- but his hometown brethren pulled through this time around!!!

The Fresh Prince was decked out in a Phillies jumpsuit and allowed his world-famous DJ to showcase his skills on the wheels of steel -- much to all the rappers' delight in the audience.

Flavor Flav couldn't contain his excitement and surprised Will on stage with a bear hug as he was finishing up his "Summertime" performance ... and was soon followed by DJ D-Nice, Chance The Rapper and tons of other giants of hip hop!!!

Will and Jazzy Jeff won the first Grammy presented for Best Rap Performance with 1988's "Parents Don't Understand," and were also the first hip hop act to perform at the awards.

The special is set to air on Paramount+ in December and also features Queen Latifah, E-40, Rakim, Latto, Big Daddy Kane, DJ Quik, Too Short, Remy Ma, YG, GloRilla, Gunna and many more.

Former NFL player Matt Ulrich -- who won a Super Bowl with the Indianapolis Colts in 2006 -- has died, Jim Irsay announced Wednesday. He was 41 years old.

Details surrounding his death have not been revealed at this time.

Irsay shared his condolences on X just minutes ago ... saying even though the offensive guard was with the team for a short time, his presence was felt throughout the organization.

"I am heartbroken to hear of the passing of Matt Ulrich," Irsay said in a heartfelt post. "Matt was with us only two seasons, but left his mark on many."

"Great guy, I hear he was a great dad---and he was a Super Bowl champ.  My prayers to his family. 🙏"

Ulrich was a star athlete at Streamwood High School in Illinois ... receiving high honors in football and shot put before attending Northwestern.

Ulrich -- who went undrafted -- joined Indy in 2005 ... appearing in 10 games in his career, winning it all alongside Peyton Manning and Co. at Super Bowl XLI.

He started a fitness company in retirement ... and also ventured into business.

A fundraiser was set up to support Ulrich's family following the athlete's sudden death ... with nearly $30,000 being raised over the past 18 hours.

Tom McMakin -- the CEO of Profitable Ideas Exchange, where Ulrich worked -- donated $20k for the cause. TMZ Sports spoke with McMakin ... and he said Ulrich had the biggest heart in Montana.

"Matt had love and energy for everyone he met," McMakin said ... adding Ulrich was heavily involved in the community by coaching his kids' football teams and providing speed and strength training for young athletes.

McMakin also praised Ulrich's brain and leadership -- assisting on multiple boards for causes throughout the area and raved about his success in the office.

"An NFL lineman is usually scary ... but Matt immediately put you at ease," McMakin said. "He was a gentle giant."

Tom also commended Ulrich for continuing to focus on his health following his playing days ... pointing out the athlete had lost 40 pounds in recent years and was in "peak condition."

As for why he decided to make the substantial donation, McMakin said, "He helped build our company and he was the heart and soul to the business. It's the least we could do."

Emotional day for Aaron Carter's family ... with his son visiting the late singer's grave site, exactly one year after his death.

Sunday marked the first anniversary of Aaron's passing, and his fam stopped by his headstone at Forest Lawn Hollywood Hills.

Aaron's ex-fiancée Melanie Martin brought their son Prince with her ... and folks who were there tell us Aaron's twin sister, Angel, was already at the gravesite when Melanie and Prince arrived.

In addition to Aaron's mourning family, we're told fans also showed up to pay their respects ... many leaving candles and flowers.

TMZ broke the story ... Aaron was found dead in his Lancaster, CA home Nov. 5, 2022, and the official cause of death was drowning as a result of being under the influence.

On Aaron's death anniversary, we're told Prince walked up to his father's gravestone and counted all the candles left by fans -- there were 20 -- and Melanie hung around until the cemetery closed for a private moment at Aaron's grave.
