Stars partied the night away inside Elton John's Academy Awards viewing party at West Hollywood Park yesterday. Gwen Stefani mingled with the evening's host Elton and his husband David Furnish, who brought their son Zachary to check out the fun for the first time. Anna Paquin and Stephen Moyer cozied up between performances by Foster the People, while Miley Cyrus and Kelly Osbourne shared a laugh on the dance floor. Nina Dobrev and Ian Somerhalder got in on the charitable action when they auctioned off a vampire bite that fetched $80,000 from the crowd. Katy Perry bid $50,000 on cooking lessons but lost to producer Steve Tisch, though the duo apparently decided to spend $100,000 and split the prize. Models Heidi Klum and Bar Refaeli snapped pictures for Twitter before Bar and Brooklyn Decker switched venues and popped up at Vanity Fair's Oscar bash at Sunset Tower. There were plenty more parties around town, including George Clooney's own event at Craig's that was attended by Brad Pitt, Angelina Jolie, Emily Blunt, and John Krasinski.
