Rosario Dawson met up with ex-boyfriend Danny Boyle to premiere their new film, Trance, in NYC last night. She was joined by her costar Vincent Cassel as she joked around on the red carpet while wearing a stunning Bottega Veneta pink dress. Later, Rosario, Danny, and Vincent headed to the premiere's afterparty where the actress celebrated the arrival of a pizza delivery by cheering for joy. The cast weren't the only stars who attended the event, with The Walking Dead's Norman Reedus arriving on the arm of Debbie Harry, and Girls stars Jemima Kirke and Zosia Mamet catching a screening of the new flick.

The premiere comes hot on the heels of the announcement that Rosario and Danny had broken up, although it isn't clear how long the couple had been dating. The two were last seen together when Rosario donned a bikini during a vacation in Barbados back in January. There are rumors that Rosario is moving on with Michael Fassbender after the two were spotted together in London over the weekend.

Michelle Williams stopped by The Tonight Show studios in LA yesterday. The star of My Week With Marilyn spoke with host Jay Leno about her film, which has earned a great deal of praise for Michelle. She's picked up best actress nominations at the SAG, Critics' Choice, and Golden Globe awards so far. We'll find out on Jan. 24 if she can add Oscars to that list, possibly making it her second year in a row of being in the running for an Academy Award. Michelle spoke with Jay about the process of making her Marilyn movie. She admitted, though, that she didn't really try to harness Marilyn's legendary sex appeal in her own life. Michelle told Jay, "I stayed a little bit in character while I was making the movie. It makes it easier that way. I remember experimenting with it early on. What was it like to walk around like that? What were people's reactions to it? But no, I think I would have felt silly trying to pick up somebody at a bar."

Matt Damon had his wife Luciana on his arm last night for the NYC premiere of The Adjustment Bureau, which hits theaters early next month. He's been on the East Coast for the last few days doing press for the film during a break from shooting We Bought a Zoo in LA. It was an evening of work despite the Valentine's Day holiday, but Matt said at the junket on Saturday that he and Luciana don't need special occasions or big gestures. When asked what dramatic move he's made for her, Matt said, "You build your life around someone, that's pretty crazy. But it's more incrementally. There's no moment where I'm like Tom Cruise in Born on the Fourth of July running down the street in the rain . . . any minute I'm not working I go home. But we have a two week rule." They're among the many couples who are happy to show PDA any day of the year, though Matt's costar, Emily Blunt, was without her own spouse John Krasinski. She still was decked out for the screening, wearing a salmon-colored Elie Saab concoction. Emily and Matt returned to the East Coast after filming the project at iconic Big Apple landmarks last year, and their amazing access to those spots is evident in the trailer — stay tuned for more from Matt and Emily's big night on PopSugar Rush!
