Spotted: Ashley Greene Celebrating Her Maxim Cover & Mischa Barton With A New Look

Every day a multitude of stars wander through the halls of MTV News to talk about their latest projects and goof around with staff members. But sometimes we catch stars elsewhere, and that's why we put together Spotted!, a daily compendium of stars in the wild.

Robert Pattinson and Kristen Stewart's intimate Harper's Bazaar cover may have dominated the favorite "New Moon" magazine cover poll we conducted recently, but we don't think anyone would argue that costar Ashley Greene's Maxim cover was certainly the sexiest. Showing off that now-famous figure in a rouched little black dress, the "New Moon" star attended Maxim's December Issue Celebration last night at New York City's Avenue, where she partied with Selita Ebanks and "Melrose Place" actors Colin Egglesfield and Shaun Sipos. Sadly, Chaske Spencer was the only "New Moon" star who made it to his cover girl costar's fete, looking comfy and casual in a leather jacket and baseball hat.

To check out Ashley's dress, click on the photo above and find out which former CW star we caught on the street after the jump.

Someone we haven't Spotted! in a while is former "The Beautiful Life: TBL" star Mischa Barton. The actress has been keeping a low profile since her series was canceled earlier this season, but we finally caught up with her in L.A., icy beverage in hand, entering the Oscar Generale showroom. We haven't decided yet how we feel about those new bangs. What do you think? Rumors have been spreading that the remaining episodes of her defunct series will air this summer, but if you can't wait to know who her character's baby daddy is or which models get busy with each other, read our spoiler-filled interview with one of the show's crewmembers.
