Lance Bass went all out for his 46th birthday ... spending the weekend partying in Las Vegas, and getting pulled onstage by Nelly.

The NSYNC singer was at Ayu Dayclub at Resorts World on Sunday when Nelly brought him onstage for a surprise performance ... and the crowd went bananas.

TMZ obtained video of the Lance-Nelly gig ... and they performed their hit from back in the day, "Girlfriend," which was a collab between NSYNC and Nelly.

On the first day of the Diddy trial, the judge is asking prospective jurors about their celebrity knowledge and their own personal backgrounds, based on answers to a lengthy questionnaire each has already filled out ... and one candidate has an occupation and a family relation that could affect both sides of the case.

In a packed NYC courthouse Monday morning, federal judge Arun Subramanian began questioning possible jurors -- and Juror No. 2's job is particularly interesting in the context of Diddy's alleged crimes ... as is his sister's relationship past.

Juror 2 happens to be a massage therapist -- who probably knows a thing or two about baby oil, which will play a HUGE role in the Diddy case. As you know, Diddy bought baby oil in bulk to use during his "Freak Offs," which are marathon sexual encounters between Diddy, his girlfriends and a male escort, according to a federal indictment.

Led Zeppelin's Jimmy Page isn't showing a songwriter a whole lotta love over one of the band's classic hits, and now he's dragging the guitarist into federal court.

A guy named Jake Holmes filed the suit against James Patrick Page -- yeah, that's his full name -- over "Dazed and Confused" ... the song Zeppelin dropped back in '69. In the docs, Holmes says it's already been legally established that he is the copyright holder on the track -- he and Page reached a settlement in 2011.

Holmes says he noticed something awry with the new IMAX documentary, "Becoming Led Zeppelin," which was released earlier this year -- the film credits say Page wrote 'Dazed' and Holmes only "inspired" it, but Holmes says that's patently false.

The first day of the federal racketeering and sex trafficking trial of Sean "Diddy" Combs began this morning with some lighthearted comments by the judge ... who mentions Diddy's various nicknames over the years, and nods to the size of the potential jury pool and the length of the questionnaire each individual filled out.

As proceedings got formally underway, Judge Arun Subramanian made a remark comparing the size of the list of prospective jurors that both sides will question on the stand -- and the questionnaire of people and places in the case -- to the famously vast "Lord of the Rings" trilogy of novels.

As you know, there are many challenges on both sides for jury selection, which is expected to take several days.

Diddy will finally face a jury of his peers who will determine his fate for the rest of his life ... but finding the right jury -- for each side -- is gonna be a Herculean task.

The defense will have a much more difficult time, because there's no such thing as an unbiased jury. Good luck finding a prospective juror in New York City -- or anywhere else in this country, for that matter -- that hasn't formed an opinion about this case.

Since the public view is Diddy is guilty, prosecutors have a big edge. As for the defense, the way to go about asking questions regarding bias is NOT simply asking if a prospective juror can have an open mind. The way to do it ... they ask if prospective jurors have ever held a view that was important to them but were able to change their mind, and they need to be specific.

Jury selection just kicked off in Diddy's federal trial, and it’s a total madhouse -- with some people getting paid just to stand in line for others to snag spots inside the courthouse.

We caught the chaos at the federal courthouse in Manhattan on Monday -- some folks told us they had been in line since the night before, saving spots for people who paid them to do the heavy lifting.

One line-holder told us he was getting $32 per hour to hold a place in line, though he admitted the going rate is more like $25 per hour. Any bit of extra income helps with inflation, particularly in Manhattan! Another clip on X showed just how absurd the line was to get into the courthouse for the jury selection ... so paying someone to save a spot makes sense.

Justin Bieber was photographed having what appears to be a smoking good time with some buddies in a secluded house, prompting feedback from a few of his fans about his possible marijuana use.

The Grammy-winning musician posted several Instagram pics over the weekend, showing him hanging out in a recording studio in a mountainous region with Aussie singer Eddie Benjamin and another dude.

Bieber's reportedly somewhere in Iceland ... and, in one of the snaps, Bieber is seen kicking back in a chair and taking a hit off what looks like a bong. Another photo captures Bieber standing next to Benjamin, who is puffing on a cigarette, as the other guy sits on a couch. A third photo features Bieber gazing into the camera, while wearing baggy sweats with a pink skull cap.

The fashion elite hit the Pre-Met Gala Dinner -- and the style game was already fire before the main event even kicked off.

It all popped off at Vogue queen Anna Wintour’s pre-Met gala at her NYC home Sunday -- A$AP Rocky rolled in sharp as ever, while Serena Williams served full glam in a bridal-esque gown with a dramatic feathered shrug.

With A$AP in the building, you know Rihanna wasn’t far behind -- rocking an androgynous-chic look with a belted blazer, tailored slacks, and a poppin’ red lip.

Kevin Costner's more rolling stone than a 'Yellowstone' ... 'cause he's seemingly flirting with a women at bars -- and, we've got photos that show the whole interaction.

The actor was photographed inside Raspoutine Night Club in Los Angeles Saturday night ... getting close with a lady in the popular spot.

Check out the pics ... Kevin's hanging out around the dancefloor -- vibing to the music while the women around him shake it.

Lady Gaga knew nothing about the alleged bomb plot at her concert or even in the immediate aftermath ... 'cause TMZ has learned cops didn't say anything to her -- she found out from the media!

A rep for the singer-songwriter tells TMZ ... the whole team learned of the alleged threat from news reports that surfaced this morning -- prior to and during the show, they didn't hear anything from the police or other authorities regarding potential risks.

So, Gaga didn't get the chance to choose not to perform -- 'cause she was sent out there without any knowledge of what might happen.

Seal and Heidi Klum's daughter turned 21 over the weekend, and it was complete with a heartfelt serenade from her famous father.

The model celebrated her milestone birthday in the early hours at Miami club, E11EVEN. Leni showed up around 1 AM in a party bus with around 20 friends.

The group sat at a VIP table, where a glowing sign bearing Leni’s name lit up and a parade of oversized alcohol bottles set the tone for the night.

Police in Brazil claim they disrupted a violent plot to detonate explosives at Lady Gaga’s record-breaking free concert that drew an estimated 2 million fans in Rio de Janeiro over the weekend.

According to Rio de Janeiro’s state police ... two people were arrested on Sunday in connection with the alleged planned attack, which was reportedly planned by a radicalized group that promoted hate speech against the LGBTQ+ community.

The officials said the group had been attempting to recruit teenagers online, encouraging them to participate in violent acts using Molotov cocktails and homemade explosives.

Tina Knowles found herself in a fashion mishap -- but leave it to Keke Palmer to turn a wardrobe emergency into comedy gold.

The matriarch was in Los Angeles on Friday to promote her new memoir when her strapless dress began to slip mid-conversation. Keke, who moderated the evening, leapt into action, steadying Tina and easing the moment with her signature wit.

Video posted on TikTok shows Palmer helping Beyonce's mom readjust the dress while a stylist quickly jumped in.

Sydney Sweeney continues to embrace her single status with a lively weekend in Las Vegas, attending the grand opening of a new club with Machine Gun Kelly and Patrick Schwarzenegger.

The blonde beauty shared moments on her Instagram from the opening of Palm Tree Beach Club at the MGM Grand Hotel, posting a photo with MGK and Schwarzenegger, and a video showing her letting her hair down, dancing and enjoying the party with high spirits.

Syd and MGK go a while back ... as far as 2021 when they starred together in the film, "Downfalls High," which MGK directed.

Cassie Ventura dated Diddy for more than a decade ... and, now she'll likely deliver some of the most important testimony at his federal trial, starting later this month.

The singer-songwriter has played a large role in Diddy's life no doubt ... and, we're going to recap her last couple years as they pertain to Diddy's life -- beginning in late 2023 when she filed a civil lawsuit against him.

Back in November of that year, Cassie sued Diddy ... accusing him of rape, human trafficking and other crimes. It was also the first time anyone had made mention of the alleged "freak offs" prosecutors claim Diddy had -- with Cassie claiming he coordinated sexual encounters between her and male prostitutes and pleasured himself while watching.

Hailee Steinfeld's clearly having an impact in her role as Queen of Buffalo -- Christian Benford tells TMZ Sports she's made the Bills' best player, Josh Allen, a "happier" man!!

We caught up with Buffalo's star cornerback on Friday -- and with Steinfeld dominating the box offices with her new "Sinners" flick, we had to ask how her two-year-long relationship with Allen has impacted his quarterback.

Benford told us he's noticed a much more jovial signal-caller -- explaining, "You could say he's happier. You know what I'm saying?"
