With the Oscars just around the corner, parties are gearing up in Hollywood, and one big bash kicked off on Tuesday in LA. Vanity Fair's annual Young Hollywood Party was filled with rising and A-list stars alike — including lots of cute couples. House of Cards star Kate Mara and her beau, Max Minghella, got cozy; while Dave Annable laughed with his wife, Odette, but they weren't the only sweet pairs of the night. Current and former costars mixed and mingled, with Kellan Lutz  and Maggie Grace staging a Twilight reunion, Nikita's Noah Bean and Lyndsey Fonseca getting close, and Avengers stars Cobie Smulders and Chris Evans goofing off. If that's not enough to excite you, two out of three Jonas Brothers  also suited up for the evening, with no visible bad blood between them post-breakup.
