Justin Timberlake hit the red carpet to celebrate the release of The 20/20 Experience at LA's El Rey Theatre on Monday night. He was joined by newly single Ryan Seacrest, whose split from girlfriend Julianne Hough was announced last week. Ryan interviewed Justin during the event, which will be televised on Tuesday night on The CW, and their chat confirmed that Justin is in fact planning on dropping a second part to the album later this year. Also on hand for the bash was Emmy Rossum, Anna Kendrick, Nikki Reed, and a crowd full of fans, who were treated to a concert by Justin that included a performance of "Mirrors." He had made his way west after stopping over the weekend in Austin, TX, where he held a secret Myspace event.

Selena Gomez and Kate Beckinsale attended Vogue's special dinner celebrating Alberta Ferretti's limited-edition 2013 collection in LA last night. Selena, wearing a blue Alberta Ferretti dress, posed alongside Chelsea Handler while Kate chatted up Olivia Munn. Meanwhile, Alison Brie, Brittany Snow, and Anna Kendrick — all in Alberta Ferretti — shared a few laughs as they sat front row at the special presentation.

The night wasn't just for actresses. Rachel Zoe and her husband, Rodger Berman, also dropped by the event to take some of the edge off of a hectic award season. Rachel attended the dinner while her client Anne Hathaway picked up the best supporting actress award at the Critics' Choice Awards while wearing Oscar de la Renta.

Ben Affleck was among the stars who turned out for last night's Casting Society of America's Artios Awards at the Beverly Hilton Hotel. He walked the carpet alongside other actors like Armie Hammer and Anna Kendrick. Ben was on hand to accept honors for the big-screen stars he assembled for his latest directorial project, Argo. His leading man from another endeavor, The Town's Jeremy Renner, was there to present Ben's statue.

We caught up with Ben before the award-giving commenced, and he dished all about Argo being No. 1 at the box office. Ben told us, "I was very excited, to be honest. I'm usually insecure, skeptical, or try to find the worst about it — but this was just a really nice thing. A lot of people worked really hard. Dramas like this don't really work well at the box office. Usually, it's more high-concept things. I was just really happy. I cut out and pasted a copy of the web page to keep it. Next time I want to make a movie like this, I want to say, hey look — you can be successful with movies like this."

Robert Pattinson attended Elle's Women in Hollywood last night as one of the few male attendees. He was on hand to honor his Bel Ami leading lady, Uma Thurman. Robert Pattinson sung Uma's praises in the role, saying their director sought "someone more intelligent, more charming, wittier and better in bed than me, which was obviously very difficult to cast." He also joked about being nervous, saying, "I'm learning how to read tonight. I find this terrifying." He didn't need to be worried, since plenty of ladies seemed happy to keep him company. In addition to chatting with Uma, Rob posed for photos with Jaime King and his Twilight pal Anna Kendrick. Rob's real-life leading lady, Kristen Stewart, skipped the event. Kristen and Rob have been hanging out, though, enjoying nights and afternoons out together around town.

Kristen Bell stepped out to premiere her short film for Target, Falling For You, at Terminal 5 in NYC last night. Kristen had the support of Anna Kendrick on the red carpet, and the pair chatted and laughed their way into the party. Rose Byrne, AnnaSophia Robb, and Nia Long also stepped out for the bash. Kristen stars in the Target movie, which was directed by Mad Men's Phil Abraham, and she actually premiered the piece with the help of fiancé Dax Shepard last week in LA. Anna, meanwhile, is coming off of her own promotional tour for her latest box office hit, Pitch Perfect, which hit the big screen last Friday.

The cast of Pitch Perfect hit the red carpet for their LA premiere last night. Elizabeth Banks wore a sexy black Alexander McQueen dress for the occasion and posed with costar Adam DeVine, while Rebel Wilson, in ABS, got together with Anna Camp, who will return to the small screen in The Good Wife on Sept. 30. Anna Kendrick arrived in a nude Zuhair Murad look and later changed into a black number to party with her costars and director Jason Moore. Brittany Snow was also on hand to celebrate the movie's debut ahead of its limited release this Friday — take a sneak peek at Pitch Perfect and other Fall films!

Jake Gyllenhaal joined his End of Watch costars America Ferrera, Anna Kendrick, Michael Peña, and Cody Horn last night for the film's LA premiere. The actors welcomed an eclectic mix of special guests, including Arnold Schwarzenegger, 50 Cent, Cody's Magic Mike costar Joe Manganiello, and Jake's longtime friend Busy Philipps. It was the movie's stateside debut after the cast premiered the film at the Toronto International Film Festival earlier this month.

We caught up with Jake and Michael on the red carpet, where Jake spoke to the "life-changing" experience of making the film. He told us he spent five months preparing for the shoot, which lasted less than 22 days in total. He and Michael play LAPD officers in the movie. The world of law enforcement and street crime was a familiar one for writer-director David Ayer — he also penned Training Day. Stay tuned today for PopSugar Rush to see more of our interviews with Jake and the cast.

Dianna Agron led a pack of ready-for-Summer stars who attended Coach's Summer Party on the High Line in NYC yesterday. The public park was closed off for the event and filled with carnival games, like a dunk tank and fortune teller's booth. Penn Badgley attended without girlfriend Zoe Kravitz, and showed off a seriously bushy beard. Maggie Gyllenhaal also stepped out to check out the scene, as did Anna Kendrick, Kate Mara, Jessica Stam, Benjamin Walker, and more. Many of the ladies made the rounds carrying pieces from Coach's new Legacy Collection. Anna is hanging out in NYC after a clip from her new movie dropped this week. The Pitch Perfect trailer came out Friday, showing Anna taking a page from Dianna's series Glee and joining an all-girls music group.

Cameron Diaz and several of her What to Expect When You're Expecting costars hit the red carpet in London today to bring the romantic comedy to England. Cameron sported a sexy, strapless Stella McCartney jumpsuit for the British unveiling of the film. She's been busy promoting the adaptation of the best-selling book in the States for several weeks already. Cameron stopped by Chelsea Lately to dish on her own feelings about family and motherhood, and also teamed up with her costar Jennifer Lopez to pay a visit to The Ellen DeGeneres Show.

Jennifer had to skip the overseas trip this week and stay put in LA for the finale episodes of American Idol, which air tonight and tomorrow. While Jennifer missed out on today's festivities, Anna Kendrick, in Christian Dior, and Chace Crawford, who play a couple in the movie, were on hand. So were Matthew Morrison, Cameron's love interest in the movie, and Rodrigo Santoro, who plays J Lo's husband.

Cameron Diaz and Jennifer Lopez, in Maria Lucia Hohan, hit the red carpet in LA last night for the West Coast premiere of What to Expect When You're Expecting, which is out in the US Friday. Last week, Cameron debuted the movie in NYC along with a handful of their many costars, like Chris Rock, Chace Crawford, Brooklyn Decker, and Elizabeth Banks. This time around, Cameron had J Lo on her arm for pictures. An Alexander McQueen-clad Elizabeth and Brooklyn, in Giambattista Valli, were also on hand again, as was Wendi McLendon-Covey, Rodrigo Santoro, and Matthew Morrison. J Lo's boyfriend Casper Smart was also seen hurrying down the press line on his way inside Grauman's Chinese Theatre.

We caught up with many of the stars before the screening began. Brooklyn spoke about how wearing a prosthetic belly in the film wasn't great practice for actual motherhood, while new uncle Chace Crawford, whose sister Candice had her first baby in April, said he's personally conflicted about being a real father. Matthew, meanwhile, revealed he's known that Kate Hudson will be on Glee since she spilled the beans at the White House Correspondents' Dinner! Stay tuned for all of our interviews on PopSugar Rush later today.
