Angelina Pivarnick lived every millennial's dream by joining Backstreet Boys' AJ McLean and *NSYNC's Joey Fatone for a show ... and yes, she rocked out like any of us would.

TMZ has obtained video featuring the "Jersey Shore" star enjoying a boy band-filled gig in Newark, NJ last week ... where Joey and AJ teamed up for a concert at the New Jersey Performing Arts Center, and where Angelina was front and center as a megafan.

It seems her adoration for the fellas paid off ... 'cause they brought her onstage to sing and dance ... and she did plenty of both.

Beyoncé's new album is a hit on streaming services, including perhaps the most important one out there ... snagging a day-of record for 2024 thus far, pretty darn impressive.

The singer's latest project, "Cowboy Carter," became Spotify's most-streamed album of 2024 in just a single day since its release on Friday ... and the numbers are out of this world. Per streaming data, 'CC' was streamed 76.13 million times since it dropped on Spotify.

That's way higher than what her last album "Renaissance" did on Spotify in just a single day -- about 43 million streams at the time -- and is far and away the biggest release this year.

Lizzo may be taking a big step back from the limelight ... as she announced she was quitting being famous in a disheartening post Friday on social media.

The Grammy winner shared on Instagram she was over the online chatter about her appearance ... and slammed people who were spreading lies about her for clout. According to Lizzo, she has been feeling disrespected after being the butt of jokes and having her character ripped apart by strangers.

She added ... "All I want is to make music and make people happy and help the world be a little better than how I found it. But I'm starting to feel like the world doesn't want me in it."

Beyoncé has done a lot with her new album -- especially for Black country artists who might've been discouraged from diving into the genre ... so says one of her collaborators.

We talked to singer Tiera Kennedy Friday on "TMZ Live," the same day Queen Bey dropped 'Cowboy Carter' to widespread acclaim ... and she tells us working on the pop star's new project was a dream come true.

Tiera, who appeared on the "Blackbird" cover, says she never would've thought she'd be on a Beyoncé track -- let alone in a country capacity -- but says the fact that it happened is wild (in a good way, of course).

Hailey Bieber has once again stirred up Selena Gomez feud rumors ... this time inadvertently pulling Beyoncé into the mix.

People are just about losing it over Bey's new cover of Dolly Parton's hit, "Jolene" -- including Justin Bieber's wife ... who posted the track on her Instagram Story on Thursday.

HB resonated with the song -- which addresses themes of infidelity and manstealing -- as she wrote "whew" alongside the single. It didn't take long for fans of Selena to interpret the comment as a dig at Selena ... who was famously Justin Bieber's ex, pre-Hailey.

Billie Eilish is calling out artists for re-releasing their music in various hard copy forms -- and while she doesn't names names ... many are taking this as a shot at Taylor Swift.

The singer did an interview with Billboard -- and she touched on this issue bluntly ... saying there are a lot of "big artists" who re-release all of their music multiple times, including on vinyl, and Billie thinks it's a shameless cash grab ... not to mention bad for the environment.

She says ... "We live in this day and age where, for some reason, it’s very important to some artists to make all sorts of different vinyl and packaging … which ups the sales and ups the numbers and gets them more money and gets them more."

Beyoncé took Dolly Parton's most famous hit about begging a woman to stay away from her man and switched it up -- going on the offensive ... and invoking the notorious "Becky."

It was one of many surprises on Bey's new album "Cowboy Carter" -- with her track "Jolene" not necessarily being a pure cover of DP's iconic song ... but more so a remix, where she drastically changed the lyrics and shifted the focus over who the song is really about.

Whereas Dolly's version is quite literally pleading with a woman named Jolene -- who's portrayed as a beauty who's seducing Dolly's fictional husband -- Bey did the opposite ... and fired off warning shots to this "Jolene" and told her to steer clear from her own hubby.

Beyoncé was living the high life ... hopping on board her $40 million private jet to indulge in some serious spaghetti ahead of her album release -- which actually features a track dedicated to the Italian culinary favorite.

Judging by her IG pics Thursday ... it looks like Queen Bey wasn't wasting any time celebrating the early success of her country-themed album "Cowboy Carter" -- set for release Friday -- as she dined in style in the air.

In another pic, Beyoncé's fully embracing the cowgirl vibe ... rocking a black jumper dress, knee-high Jimmy Choo boots, and topping it off with a stylish black fedora hat.

John Lennon pulled no punches about how much he detested the Beatles' 1964 knockout photo shoot with Muhammad Ali ... that's according to the guy who snapped those iconic images.

Famed Beatles photog Harry Benson spilled the tea on the tension between the legends while celebrating 60 years of snapping pics of the band, telling Fox News Digital ... Ali wasted no time throwing shade, telling the singers their music wasn't all that.

Not only did he hit the Beatles where it hurt by questioning their musical chops, but Ali also went on to size them up, calling them "tiny, small, little men" compared to his towering frame.

Shakira gave a real treat to New Yorkers Tuesday night ... putting on a surprise performance in Times Square for 40,000 screaming fans.

The Grammy-winning singer hit the TSX stage at the Crossroads of the World in Midtown Manhattan just hours after she announced the pop-up show on the social media app, "X."

Thousands of her followers rushed to see Shakira's spur of the moment concert as she celebrated the release of her new album, "Las Mujeres Ya No Lloran."

Tana Mongeau is having a good laugh at the expense of fellow internet star JoJo Siwa  ... who's now trying to be "bad" after years of being cute, cuddly and kid-friendly.

Tana posted a video over the weekend mocking JoJo's new song "Karma" -- in which she's reciting some of the lyrics ... and then posing a question on whether JS is actually a "bad girl" now as she proclaims.

There's another video Tana posted that continued to poke fun at JoJo's song ... you can clearly tell TM's not taking JoJo seriously, and she thinks she's jumping the shark here.

Maluma's totally vibin' as a girl dad ... calling it the highlight of his life, and he's got the pics to back it up.

Just over 2 weeks after her birth, the Colombian singer dropped a carousel of pics with his adorable newborn daughter, Paris, and his GF Susana Gomez ... and his caption is just pure gushiness!

"Mis primeros 15 días como Papá, esto es lo mejor que he vivido en mi Vida.. 💘," he wrote in Spanish ... which translates to, "My first 15 days as a dad, this is the best thing I have ever experienced in my life."

For all you Mozart buffs out there, there's a piece of memorabilia up for grabs: his signature -- but here's the catch -- you need some seriously deep pockets if you want to snag it.

Gotta Have Rock and Roll has the legendary composer's signature up for auction -- and it's expected to fetch anywhere from $100k to a whopping $200k -- with the bidding kicking off at $75,000.

Mozart's signature, written in black ink, has been authenticated and graded (NM-MT 8) by PSA/DNA, the top dog in third-party authentication for autographs and memorabilia. So, rest assured, it's the real deal!

Mozart's full name was Wolfgang Amadeus Mozart, and he's widely regarded as the most influential Austrian composer of the Classical period ... and his musical legacy continues to resonate and inspire to this day.

Despite his short life -- he passed away at just 35 in 1791 -- Mozart's incredible productivity led to over 800 works spanning nearly every classical genre of his era.

Rihanna seems to be putting an age-old theory to the test ... finding out if blondes really do have more fun -- 'cause she's rocking a short, light new hairdo!

The singer-songwriter stepped out in Santa Monica Friday, and her new look was instantly noticeable -- RiRi's usually lettin' her long locks flow, but now ... she's trimmed most of it off.

Just check out the pics ... her hair's not even touching her shoulders at this point -- a pretty sharp contrast to the Rihanna we normally see these days ... who lets her hair fall all the way to her hips. That's the 'do she's been sporting lately, anyway.

Also, peep the jewelry ... Rihanna's iced out with a necklace, earrings and bracelets -- shining bright like a diamond while on her way to an important meeting. It definitely accentuates the blonde hair up top ... and we gotta say, she's pulling the whole look off and then some.

Rihanna's look is noticeably different from one of the last times we spotted her ... as she was leaving Mukesh Ambani's son's pre-wedding bash in India with a swag bag and at least $6 million for her performance on the special day.

No word on how A$AP Rocky feels about the fresh cut ... but when your lady's RiRi, it's hard to imagine you can criticize much about her -- 'cause she's a beauty through and through.

Celine Dion's proving she can still rock by jamming out to Bon Jovi at a Boston Bruins game ... and the heartwarming video also makes it clear she's not letting her health challenges stop her from living life to the max.

Check out the clip -- Celine didn't hold back as she started singing along to the rock band's classic "Livin' on a Prayer" Thursday night at the Bruins game against the NY Rangers ... a rare public appearance amid her ongoing Stiff-Person Syndrome battle.

Celine's right in the thick of the action at Boston's TD Garden alongside her twin sons Nelson and Eddy ... when the camera zeroes in on her as she pumps her fists in the air and claps along while singing along to the catchy tune.

Her inner rockstar comes alive in the X clip shared by fan account @celinebible ... she rises from her seat to unleash an air guitar solo that's pure magic.

You can take the girl off the stage, but you can't take the performer outta her!

Celine wasn't just there to watch the game ... she and her sons got the royal treatment from Bruins coach Jim Montgomery, who introduced them to the team for a legendary line-up read.

The icon's ice hockey antics came hot on the heels of her heartfelt tribute on International Stiff-Person Syndrome Awareness Day ... where she thanked her family, team, and fans for all their love and support since her diagnosis.

Celine was diagnosed with SPS in 2022, and she's been fighting tooth and nail to cope with the autoimmune disorder, even pulling the plug on her tour to prioritize her health.

The truth is ... she has her good days, and bad ones too during this battle. Her sister has said at times Celine is suffering and completely immobilized.

Ricky Martin says his dad was all for him living his truth out loud ... telling him he needed to come out publicly -- this while his professional team tried to talk him out of it.

The singer sat down for an interview on Sirius XM's "Andy Cohen Live" when he opened up about deciding to come out as gay -- and he says not everyone was in alignment on whether or not he should let the world know.

Martin told Andy his professional team told him it wasn't a good idea to reveal himself as an openly gay man ... in fact, he says they were quite certain it could kill his career.

But, Ricky goes on to explain his dad understood the importance of coming out and pushed him to tell the world after his two sons were born in 2008 ... with his pops saying RM couldn't start out by teaching his children it's better to lie than be yourself.

In any case, Martin says he took his time formulating a letter to tell the world he was gay and then tweeted it out ... and he said he felt instant relief -- sobbing tears of joy.

Of course, Ricky's since had some very public relationships with men ... including his high-profile marriage to Swedish artist Jwan Yosef from 2017 ... until their divorce last year.
