For Justin Timberlake's well-rated return to "Saturday Night Live," the singer scored Lady Gaga for another digital short with funnyman Andy Samberg.

Known for viral sensations on risque subjects, duo Timberlake and Samberg work an intentionally cheesy R&B shtick with hilarious results.

Gaga was tapped as musical guest for the episode, the show's season finale, and proved more than willing to play along in a clip titled "3-Way."

Timberlake and Samberg pay tribute to the following gentleman's agreement: engaging in a ménage à trois is not gay. Not even a little. 

Gaga appears as the lady component in their comedy sandwhich, with special appearances from Susan Sarandon and Patricia Clarkson. Check out the clip above.

Justin Timberlake will be back hosting "Saturday Night Live" in all his "... In a Box," "Give It on Up" and "Mother Lover" glory, an NBC Twitter slip-up has revealed.

The singer-turned-actor, who earned two Emmys thanks to his previous stints on the sketch comedy, will be hosting for the fourth time on the May 21 season finale. He'll be live from New York a few weeks after Tina Fey is slated to host on May 7 (more Sarah Palin, please!). The news came via a wayward response on NBC's official Twitter feed.

"I didn't realize that @nbcSNL isn't back until May 7th!!! What am I going to do!? Is Tina Fey the season finale!?" a fan wrote.

"Nope! We have Timberlake after that!" was the response, which has since been removed from the micro-blogging site.

His musical guest will be Lady Gaga, who has been just about everywhere promoting her "Born This Way" album. Gaga last performed on the "SNL" stage in 2009.

If Timberlake is indeed the host, we hope Gaga jumps into some of his sketches.

Which sketches are you hoping the "SNL" writers will bring back for JT or do you prefer his digital shorts with Andy Samberg? We want to know in comments.

Demi Moore and Ashton Kutcher have launched a flurry of PSAs featuring such A-listers as Justin Timberlake, Drake and Bradley Cooper to put an end to human trafficking and child sex slavery.

The DNA Foundation's Real Men Don't Buy Girls Campaign launched Monday and has been gathering steam. Kutcher kicked off the campaign with his "Real Men Do Their Own Laundry" video. Subsequently, Isaiah Mustafa, Jason Mraz, Adrian Peterson, Sean Penn and Jamie Foxx have each been featured in PSA videos. See all the real men (and the women who prefer them) here.

The philanthropic couple will appear on Piers Morgan’s show this week and have enabled supporters to their own “real men” videos too.

"Many people think of human trafficking as a problem in developing countries. The sad reality is that thousands of young girls have been forced into sex slavery and held against their will, right here in the 'land of the free,' " Moore and Kutcher said in a statement.

"After learning about this horrifying problem, we realized that we couldn't just go on with our daily lives, we had to do something about it. And we've enlisted government, law enforcement and nonprofit organization experts to help."

The couple recently traveled to Luxor, Egypt, to attend the International End Human Trafficking Now Forum. The also spoke at the launch of the United Nations Global Plan Against Trafficking in Persons and Victim's Trust Fund last November, working to provide "humanitarian, legal and financial aid to victims of trafficking."

Which "real man" is your favorite? Tell us in comments.

Justin Timberlake and Olivia Wilde are enjoying their new status as singles -- together.

The sexy pair rolled out to the Roxbury on Saturday, seated together in the VIP section of the Hollywood venue. Both rocking casual jeans and T-shirts the twosome "snuggled" at one point, an eyewitness tells the Ministry.

Sipping vodka, Timberlake led Wilde from the VIP to an outdoor patio around 1 a.m. so the actor/singer could better hear a hip-hop set from the DJ. They left together around 3 a.m.

While our partygoer witness insisted the pair were on a date, a source told People magazine the stars are just friends, and have been since meeting on the set of 2006's "Alpha Dog."

Wilde dropped a bombshell in March by filing for divorce from Italian royal Tao Ruspoli -- the husband no one quite knew she had. Timberlake announced his own split from longtime girlfriend Jessica Biel in mid-March.

Justin Timberlake and Jessica Biel have split up, their reps confirmed Thursday — and though breakup rumors have swirled for many moons, there's apparently no need to expect any big drama now.

"The two remain friends and continue to hold the highest level of love and respect for each other," the couple's reps said in a statement. Timberlake and Biel have been together since 2007, and in February both attended the Vanity Fair Oscar party.

A source told People that the decision was "completely mutual" with "no hard feelings."

That's a change from the last time around for Timberlake, seen recently in "The Social Network."

The singer and actor had dated Cameron Diaz for almost four years — and then a month after they'd split, Diaz notoriously and publicly argued with her ex at a Golden Globes after-party, where he was chatting with Biel.

Amanda Seyfried is not the coy girl she once seemed to be: The "Red Riding Hood" actress will kiss and tell, especially when her leading men are Hollywood hotties such as Ryan Phillipe, Channing Tatum, Justin Timberlake and Dominic Cooper.

Seyfried, who's done soap operas, musicals and television, is channeling her pristine star power this month in a grown-up, spooky version of the children's story, directed by "Twilight" alum Catherine Hardwicke.

The 24-year-old "Big Love" actress and April's Elle cover girl -- styled in Dolce & Gabbana and Alexander McQueen while toting various furry critters -- opened up to the mag about being inspired by Meryl Streep, not wanting Botox and how she can't help falling for her leading men.

"[It is] one of the easiest things in the world. You're both open. You're put in a situation where you have to make out with each other. It's easy for things to get carried away," she said.

Her best on-screen kisses? "I can't lie. It didn't suck making out with Channing [Tatum] and Justin [Timberlake]."

For those trying to keep track, she did "Dear John" with Tatum and will costar with Timberlake in "Now."

And what of her roller coaster of a relationship with Cooper, her "Mamma Mia!" costar? Seyfried spoke candidly on the tumultuous romance and impending fallout that occurred when she thought he would break up with "Mean Girls" castmate Lindsay Lohan for her.

"I was just kind of foolishly thinking that the two of them were done and Dom and I were involved," she said. "But we weren't really as involved as I thought. So I got my heart broken pretty hard," she said. She and Cooper eventually got together, but "then it took a long time for us to break up again. After that, it's really hard to open myself up to a new person. Really hard."

In the meantime, she dated Alexander Skarsgard, but said she "was too involved with Dom."

So is she now dating Phillippe? "Um, yeah. I've been 'seen' with him," she said.

The issue hits newsstands March 22.

With a giant photo of actor James Dean looming over the entrance to Los Angeles' Sunset Tower Hotel, Vanity Fair welcomed an army of stars to its 2011 Academy Awards post-party.

Notoriously exclusive and always glamorous, the annual event did not disappoint as big winners including Natalie Portman, Colin Firth, Melissa Leo and director Tom Hooper came with trophies in hand to greet Editor in Chief Graydon Carter.

Portman was naturally the belle of the ball, hand-in-hand with fiance Benjamin Millipied as countless people congratulated her on her awards-season sweep.

Jude Law palled around with Cameron Diaz and "Contagion" costar Gwyneth Paltrow while Gabrielle Union chatted with Jamie Foxx -- who then ran into his friend Jessica Biel. Biel and Foxx  went off together to circulate while Justin Timberlake stood with Andrew Garfield and his girlfriend.

Gorgeous women weren't in short supply, including newly single Scarlett Johansson, who was engaged in deep conversation with Tim Burton and Helena Bonham Carter. Though this was Portman's year, few could quite contain themselves when nominee Michelle Williams floated by.

In stunning Chanel haute couture, Williams had a soft glow that stopped conversations and, frankly, assured us she'll make a convincing Marilyn Monroe in the forthcoming "My Week With Marilyn."

Let us not forget Williams' humble roots, however: She looked right at home speaking with former "Dawson's Creek" costar Busy Phillips. 

Star couples -- including Tom Hanks and Rita Wilson, designer Tom Ford and Richard Buckley, Reese Witherspoon and Jim Toth, Jon Hamm and Jennifer Westfeldt, Liev Schreiber and Naomi Watts, and Judd Apatow and Leslie Mann -- put up unified fronts.

But no couple was so convincing as Justin Bieber and Selena Gomez, the picture of young Hollywood come to the grown-ups' table, running back and forth between the Tower bar and terrace holding hands (yes, they were). Taylor Swift made an appearance in a gold mini, snacking from a cone full of In-N-Out Burger fries that was getting passed around. Meanwhile, her former flames Jake Gyllenhaal and Joe Jonas worked the crowd. 

It's a good year to be a television star, being that many small-screen favorites were invited to film's big night: Sofia Vergara of "Modern Family" and "Glee" folks including Lea Michele, Chris Colfer and Matthew Morrison made the scene.

Fellow gleek Dianna Agron showed up, looking nowhere near as traumatized as some since-debunked reports would have her after her split with actor Alex Pettyfer. 

As Justin Timberlake marked his 30th birthday Monday, he woke up with the party behind him — the People magazine/EIF-hosted SAG Awards after-party, held in a gala tent outside the Shrine Auditorium on Sunday.

Timberlake stuck close to "Friends With Benefits" co-star Mila Kunis, lounging in a booth with her "Black Swan" director Darren Aronofsky.

His "Social Network" pals Andrew Garfield and Jesse Eisenberg rolled through, bobbing and weaving through the night's big ensemble winners from "Modern Family," including Eric Stonestreet, Sofia Vergara, Ty Burrell and Julie Bowen, toasting with Champagne and Grey Goose cocktails.

A baby-bump-baring Jane Krakowski chatted with Matthew Morrison while his fellow "Glee" stars Jane Lynch and Lea Michele circulated. Tons of folks commented on how sweet "The Kids Are All Right" actors Annette Bening and Mark Ruffalo looked, talking closely and holding hands.

After the bash, select SAG Awards-goers hit the Chateau Marmont for a nightcap, including Chris Colfer and Amber Riley of "Glee," "Black Swan" king Aronofsky and Christina Hendricks, as well as "Dexter" stars Michael C. Hall and Julia Stiles — who arrived together — just before last call.

Justin Timberlake's role in the upcoming "Yogi Bear" feature film isn't exactly as weighty as his portrayal of Napster founder Sean Parker in "The Social Network," for which he's been receiving industry praise. But although his cartoon effort might not earn him an Oscar nomination, the 29-year-old said the role of Boo-Boo required a fair amount of preparation.

"It was one of those things where his voice actually -- if you really wanna know -- his voice is in a certain register, so it took me about 20 to 30 minutes to get my voice warmed up into that register," Timberlake said at the "Yogi Bear" premiere Saturday in Westwood.

The actor was joined on a brown carpet by costars Anna Faris, Tom Cavanagh and Dan Aykroyd, who tackles the voice of Yogi in the movie. Aykroyd, who said he had been busy working on a script for "Ghostbusters III," followed "Yogi Bear" from its early stages of development because the program was one of his childhood favorites.

"I grew up with it as sort a subliminal part of my character, watching it every afternoon between the key ages of 8 and 12 in Canada, where the sun left the sky at 3:45 in the afternoon in February," Aykroyd said. "I'd walk across the frozen creek, up the frozen stump trail, past the den of wolves. I lived on the edge of a national park, and I'd strip off the frozen snowsuit, turn on the little black-and0white TV, and there were Yogi and Boo-Boo to warm me up after my hard day at school and my rough commute."

Cavanagh, who has a live-action role in the movie as a park ranger, said he was proud of the film -- though he joked that he was bothered by one of his costars: Timberlake.

"Here's what I think about Timberlake: He dominates the musical field, now he's gonna dominate the acting field," Cavanagh said. "Good looking, great athlete. I mean, it's extremely annoying."

Had he ever voiced these concerns to J.T. himself? "Not to his face," the actor said. "He's a very powerful man. I want to keep working."

As Justin Timberlake continues his push for award-season glory and puts film at the forefront of his career, he has an ally in costar Mila Kunis.

Timberlake himself recently admitted to The Times that he's "obviously not the best actor," but Kunis begs to differ.

"I think he's one of the more talented people I've ever worked with," she told the Ministry on Thursday, celebrating her Nylon magazine cover at a dinner in Hollywood hosted by Armani Exchange.

"I have confidence in him [as an actor], I think he's smart, talented and has so much more to show the world."

Timberlake and Kunis get hot and heavy in their upcoming comedy "Friends With Benefits," about a platonic pair who use each other for sex devoid of emotional attachment -- or so they think.

Kunis is no stranger to comedy, given her breakout was "Forgetting Sarah Marshall" opposite Jason Segel. She held her own with the laughs, but finds drama easier to handle.

"When you have 19-, 20-hour days, you get loopy," she said. "You think the work is funny because you're tired ... it might not be that funny a year later on the screen."

We'll see what happens in July, when "Benefits" hits theaters.
