Robert F. Kennedy Jr. just wished his second-oldest son, Conor Kennedy, a happy birthday ... blessing us with a collage of hot shots that truly show just how strong that Kennedy DNA is.

RFK Jr. posted a b-day shout-out Saturday to his boy to celebrate his 26th birthday, writing ... "Happy Birthday,Conor! #condorkennyabish Nakuruai." He also attached several photos of the handsome young buck, several of which showed CK looking hunky and shirtless.

Look, the guy is VERY good looking -- we'd say like father like son, but with this family -- it's more along the lines of ... like Kennedy like Kennedy. Just a bunch of handsome dudes.

In Conor's case ... he's no exception. Some of the photos his dad posted showed him with his sister, Kyra, his brothers William and Aidan and his niece Bobby. The new generation of Kennedys are pretty tight it seems -- and the family seems to only get bigger by the year.

Now, Conor here has already sorta broken through the fame threshold ... even at his relatively young age. The guy dated Taylor Swift briefly in the summer of 2012 -- and by all accounts, she was pretty smitten with him. This was on the heels of his mother, Mary Richardson Kennedy, passing away by suicide -- which left him and his siblings grief-stricken.

Taylor was reportedly a rock for Conor during that difficult time, but things seemed to turn when she bought a house in Hyannis Port, MA ... literally a few houses away from the Kennedy compound, where Conor lived. There were reports ... it made him "nervous."

That's all water under a bridge now though -- he's moved on, and so has Taylor, obviously. Conor's since beefed out to be quite the man. If you need more proof, his stepmom, Cheryl Hines, posted even more throwback photos/thirst traps of the kid ... and yes, they too are to die for.

'Love & Hip Hop' star Mariahlynn claims her ex and his new GF beat the crap out of her and a pal with a bat and blade, leaving them bloodied and battered ... this according to cops.

Law enforcement sources tell us the reality star filed a police report this past week alleging she and a good friend of hers were ambushed by Mariahlynn's former boyfriend, whom she says had invited her over to his place in the Bronx to hash things and make peace.

We're told Mariahlynn described an incredibly horrific sequence of events to police ... she said as soon as she and the woman she was with arrived at the ex-boyfriend's apartment, they were immediately jumped by both him and his new girlfriend, who allegedly pulled out a blade and even used a bat to beat the two women before they escaped.

Sources with direct knowledge tell us ... Mariahlynn was punched in the face, kicked in the back of her leg, dragged by the hair and held down so the other woman could pile on. We're told Mariahlynn's friend was beaten with the bat and brutally attacked too.

We’re told Mariahlynn has multiple contusions, a fractured leg, a cut face and a black eye. TMZ obtained photos of injuries Mariahlynn claims resulted from the alleged beatdown -- as you can see, they're gnarly.

Our law enforcement sources noted visible injuries to Mariahlynn and her friend -- listing the alleged crimes as felonious assaults. We're told neither the ex-boyfriend nor his alleged accomplice has been arrested -- NYPD cops are currently investigating.

Naya Rivera's ex-fiance, Big Sean, has been silent about her tragic death ... until now.

Sean posted a tribute to his ex, saying, "Rest in Peace Naya, God Bless your Soul! Thank you for blessing us all with your talent and presence. You are a hero!  Not just because of how you saved your son, also because of the barriers you knocked down for so many people to make them feel confident in themselves and to stand tall and be proud when they couldn't achieve that on their own."

He goes on ... "I appreciate and cherish everything that ever happened between us for making me wiser and a better person. I'm still grieving and in shock, I can't believe this is real."

As you probably know, Naya and Sean were engaged in 2013 after dating for only 6 months. They had a bad breakup 5 months later. Naya says the end of the relationship was hurtful ... "We'd been fighting for five straight days while he was traveling, and then on the one day he was back in LA, he said he didn't want to see me."

Joey Lawrence is throwing in the towel on his second marriage ... he just filed for divorce.

The former "Blossom" star filed Friday in Los Angeles County Superior Court to divorce Chandie Lawrence as they approached their 15-year wedding anniversary.

Joey and Chandie met at Disney World way back in 1993, when he was 16 years old and on vacation. Joey says he invited her on an ice cream date at the Mouse House when they first met and joked about getting married at the theme park.

After Joey's first marriage to Michelle Vella ended in divorce in 2005, he quickly wed Chandie in July and their teenage wedding fantasies became reality as they tied the knot at Disney World.

It's not clear what led to the split, but Joey and Chandie will have to settle child custody and/or support issues -- they have 2 minor daughters, 14-year-old Charleston and 10-year-old Liberty.

Despite Disney's best efforts ... no fairytale ending this time.

Bombshell allegations from Evelyn Lozada -- who says Chad Ochocinco abused her MULTIPLE times during their relationship, despite his claims to the contrary.

Lozada -- who was married to the ex-NFL star for less than a month in 2012 -- released an emotional video Thursday claiming Chad is straight-up LYING about physical abuse in their relationship.

As we previously reported, Ochocinco was arrested for domestic battery on August 11, 2012, when he headbutted Lozada during an argument, causing a massive bloody gash.

Johnson was later cut from the Miami Dolphins as a result -- and his NFL career never really got back on track.

On Wednesday, Ocho mentioned the incident on Twitter -- saying, "I lost my temper for once in life for 3 seconds & it cost me a lifetimes worth of work."

He added, "I got it all back plus some after getting a 2nd chance & NOTHING will ever get me out of that happy space again."

The problem ... Evelyn says Chad isn't telling the truth and it's causing her tremendous pain.

"For this man to sit up there and say that he lost his temper for 3 seconds is infuriating to me," Lozada said ... "It's messages like this, tweets or whatever the hell it was, that are triggers for me."

"People read this on social media and are coming at me talking about 'oh you made this man lose his job' it's like if you're gonna speak the truth, I want you to speak the truth as to what the situation was."

"It wasn't the first time, it wasn't the first time!"

"And, one of the things I'm always gonna do is I'm always gonna live in my truth, whether it's good, whether it's bad, whether it's ugly, I'm not going to let anybody take away my f**king truth and put this perception out there for a pity party as if you made one mistake."

Evelyn continued, "And, I'm trying to move on from this. But, as a victim, how am I supposed to move on?!"

"What happened to me that day and other days, I didn't deserve. I didn't deserve that."

Tekashi 6ix9ine has a plan to reunite with his young daughter once he's got the ankle bracelet off -- whether his baby mama likes it or not.

The rapper's lawyer, Lance Lazzaro, tells TMZ ... his client is going to be part of 4-year-old Saraiyah's life one way or another in a couple weeks when he's released from home confinement. He says the simplest way to make that happen is get a judge involved to hammer out a court-ordered custody arrangement ... despite protests from his ex, Sara Molina.

Lance tells us Tekashi wants to be there for his kid -- and that the only reason he hasn't been since getting out of prison was for her own benefit. We're told it wouldn't have been prudent to have Tekashi visiting Saraiyah these last few months ... you can imagine why.

Sara says if Tekashi really wanted a relationship with his kid, there are many ways to do that ... and he hasn't to this day.

Sara tells us if 6ix9ine wants in again on his daughter's life, he's gotta play by her rules and ease back in as she sees fit ... not on his timetable. With that in mind, Sara says she has no problem if his own mother continues seeing the girl -- which has gone well thus far.

It's interesting because Sara seems willing to crack the door open for Tekashi in about 2 weeks -- but the way his attorney's talking ... it sounds like they're going over her head.

Armie Hammer and his wife, Elizabeth Chambers have both just filed for divorce.

Elizabeth filed the divorce petition, and Armie filed his answer at the same time, so it was clearly coordinated.

There are differences. Elizabeth wants sole physical custody of their 2 children -- 5-year-old Harper Grace and 3-year-old Ford. Armie is asking for joint legal and physical custody.

Elizabeth cites the usual -- irreconcilable differences -- as the reason for the divorce.

Sources connected to the couple tell TMZ ... there is NO PRENUP. Based on the documents it appears Armie will pay spousal and child support. The date of separation is interesting ... Armie lists January and Elizabeth lists July. This is a crucial difference ... if the judge accepts her version, they would have been together as a married couple for just over 10 years, and that could affect spousal support. If January is the date, it's under 10 years.

Armie said earlier today ... "Thirteen years as best friends, soulmates, partners and then parents. It has been an incredible journey, but together, we’ve decided to turn the page and move on from our marriage."

He adds ... "As we enter into this next chapter, our children and relationship as co parents and dear friends will remain our priority."

His Instagram post concludes with, "We understand this news lends itself to public dialogue, but in the interest of our children and our family, we’re asking for privacy, compassion and love during this time."  Elizabeth shared the same IG post at the same time as Armie.

At the end of May, Elizabeth posted this -- "TEN years married, twelve together, thirteen years as best friends. Happy Anniversary, my love. I’m beyond grateful for you, this decade, our family and the dreamiest Friday night anniversary sunset." Notice the all caps on "TEN" ... sure seems like she wanted to emphasize, in her eyes, they'd reached that crucial mark.

Armie, Elizabeth and their kids have been quarantining together in the Cayman Islands ... where Armie spent some of his childhood.

It's the first marriage for both Armie and Elizabeth.

Armie is repped by disso queen Laura Wasser, and Elizabeth is repped by Kristina Royce.

Kacey Musgraves' marriage to her singer-songwriter husband was less of a slow burn and more of a flame that went out quickly ... she's getting divorced after 2 1/2 years.

The Grammy-winning country star and musician Ruston Kelly have filed for divorce -- according to reps for both singers -- and say they've "made this painful decision together."

Kacey and Ruston released a statement to AP saying ... "With heavy but hopeful hearts we wanted to put our own thoughts into the air about what’s happening. These kinds of announcements are always met with scrutiny and speculation and we want to stop that before it even starts."

It continues ... "We believe that we were put into each other’s lives for a divine reason and have both changed each other infinitely for the better. The love we have for each other goes far beyond the relationship we’ve shared as husband and wife. It’s a soul connection that can never be erased."

The exes add that the decision to divorce is a "healthy decision that comes after a very long period of trying the best we can. It simply just didn’t work." They say they will remain true friends.

The couple wed in October 2017 in Tennessee, after meeting in Nashville in early 2016.

There were signs things were on the rocks as early as November 2019, when Kacey brought Gigi Hadid to the Country Music Awards as her date. The following month, Kacey removed her wedding photos on Instagram and Ruston did the same.

Christina Ricci has just filed for divorce from her husband after almost 7 years of marriage ... TMZ has learned.

The "Casper" and "Addams Family" star filed in L.A. County Superior Court Thursday morning to divorce film producer James Heerdegen, whom Ricci met in 2011 while they working on the set of the show, "Pan Am." They got married on October 26, 2013, in NYC.

Ricci cites irreconcilable differences as the reason why she wants to end the marriage. She's asking for sole legal and physical custody of their 5-year-old son, Freddie.

Our sources say there is no prenup but Christina was the main money earner. And, then there's this ... Ricci was granted an emergency protective order by cops after an altercation in which she claims James spit on her. The altercation went down exactly a week ago in her L.A. home.

Heerdegen, who was not arrested after the incident, has been ordered to stay away from Ricci.

Ricci's repped by attorney Samantha Spector in the divorce.

Brody Jenner has a new girlfriend ... she's Louis Tomlinson's baby mama, and he's already introduced her to his ex, and gotten 2 thumbs up.

Briana Jungwirth is Brody's new girl, and they had a date night Saturday at Nobu in Malibu, but it was kind of a group thing ... Brody's ex, Kaitlynn Carter, tagged along with a few other friends in tow as well.

Our sources tell us the dinner was anything but awkward. We're told Brody and Kaitlynn are still very close, they are co-parenting dogs after all, and BJ really wanted Kaitlynn's approval on his new GF, which he got.

We're told Briana seemed cool with meeting a slice of Brody's past, and she totally understood the dog situation and the fact Brody and Kaitlynn will remain in the same circles. In August, the exes are scheduled to resume filming "The Hills" together.

From Brody's point of view, we're told he wanted to introduce Briana to Kaitlynn so she'd be comfortable with a situation that is anything but standard for exes.

Fortunately for all parties, the women got along and Briana even talked about her son with the former One Direction heartthrob.

In fact, we're told when Briana brought up her son, Freddie, at the dinner table, she mentioned he'd already met Brody. So, the budding relationship already sounds serious.

Brian Austin Green and Courtney Stodden are definitely together ... in the friend zone, we're told, but they are talking about getting creative.

Sources close to the situation tell TMZ ... Brian and Courtney are just friends who met about a month ago via social media. We're told the initial communication was about sharing ideas regarding the possibility of creating music together.

We're told after some friendly chats, they decided to meet up and hang out. And, they did ... hitting up a Mexican joint over the weekend in L.A.

It helps, we're told, they also share similar political views, the kind that makes them want to make a change that's bigger than themselves. For now ... it's platonic, but things could change. That's Hollywood, baby.

Courtney, of course, is fresh off her divorce and at the moment, we're told, she's committed to herself and not looking for a relationship. As for Austin, well, you know all too well.

As we reported ... his marriage to Megan Fox is currently in separation mode. It was clear things were off after photos of Megan and Machine Gun Kelly surfaced last month. Not long after, she appeared in one of his steamy music videos.

Audrina Patridge's estranged hubby is jobless thanks to the COVID-19 pandemic lockdown, and he's now asking the court to order her to pay child support.

Corey Bohan filed legal docs in Orange County Superior Court claiming he needs the support because the lockdown orders made him among the millions out of a job ... this according to new legal docs obtained by TMZ.

In docs, Corey says he's a bartender but was laid off back in March due to the lockdown orders. He says being out of a job means his ex has to pony up for their 3-year-old daughter, Kirra, because Audrina “earns significantly higher income than” him. Corey adds, Kirra should have the right to live the same standard of living in each home.

He claims she's earning in excess of $36k per month “while I am currently laid off due to the stay at home orders and have not yet received any unemployment." Corey says even when he does get back to work, his average monthly income is around $2-$3k per month -- so, sounds like he wants support even once he's slinging drinks again.

Corey claims Audrina can afford child support because she “also owns real property, is able to fund a retirement account and has various investments." He also wants the former 'Hills' star to kick in $7,500 towards his legal fees. There's an August hearing set for his request.

Brian Austin Green's finally got a response to his estranged wife, Megan Fox, starring in Machine Gun Kelly's music video ... a date with Courtney Stodden.

Brian and Courtney were spotted together Saturday grabbing lunch from a Mexican joint near L.A. and looked like a pretty rockin' couple -- him in a Pink Floyd shirt and her in a leopard print dress.

Now to be fair, there's no indication there's anything romantic going on between them, but the sighting's still interesting ... and they're both single and ready to mingle, as far as we know.

As you may know ... Brian and Megan's on-again, off-again relationship status is currently set to off. Their marriage has been notably turbulent for years, but there were major signs they're on the rocks last month when we got photos of Fox hanging out with MGK.

Brian later revealed Megan told him she wanted to separate months ago after returning home from shooting a film in another country ... which costars MGK.

The '90210' actor suggested divorce was imminent and difficult for him to accept, but also said he was glad Megan was honest with him ... and he wasn't upset she's with MGK, who he referred to as a good guy.

Shortly after that, Fox starred in MGK's steamy new music vid for "My Bloody Valentine" ... which seemed to signify she and her hubby were officially donezo.

Ex-'Teen Mom' star Jenelle Evans appears to be leaving her volatile husband, David Eason, for good -- this after the guy allegedly pistol-whipped a man and got arrested.

We confirmed Eason was busted and booked Friday night out in Columbus County, North Carolina on two different charges -- assault with a deadly weapon and communicating threats.

As for what happened leading up to this ... reports say, and Jenelle seems to confirm on social media, that a scuffle broke out between a couple of her guy friends and David ... when she returned to the house to get some of her things. Eason allegedly pistol-whipped one of the dudes over a misunderstanding over keys.

Jenelle is reportedly staying with a relative now.

She wrote on FB, "I just want to let the public, tabloids, and my fans know that IM OK, IM SAFE AND SO ARE THE KIDS! I'm going to take a few days out to myself to gather my thoughts and focus on what's going on so I won't be on social media much. I love you all for the support that you all have shown me and I'll be stronger and better than ever soon!"

Jenelle also told Celebernation that it was time she and David went their separate ways ... again.

Cops released Eason on an unsecured bond.
