The Oscar afterparty fun kicked off in LA last night with Vanity Fair's Post-Oscar Bash! The Sunset Towers hosted celebs who attended the show, as well as those who didn't, like Victoria Beckham, Abbie Cornish and Jessica Simpson, who chatted with Heidi Klum. Sandra Bullock clutched her Academy Award, as her The Blind Side costar Quinton Aaron posed with Rachel McAdams. Kathryn Bigelow and Jeremy Renner looked thrilled to bring out their The Hurt Locker gold and fellow winner Jeff Bridges smiled alongside fellow Crazy Heart actor Maggie Gyllenhaal. Cameron Diaz changed out of her red carpet dress and into something shorter as she chatted with Jason Segel, while elsewhere Sean Penn shared a drink with Kid Rock. 
Kristen Stewart, meanwhile, chatted away alongside Anjelica Huston, as Inglourious Basterds' Eli Roth cuddled up to his new lady, Peaches Geldof. Rachel McAdams' ex Josh Lucas gave some bunny ears to Sam Worthington and Carey Mulligan, while happy couples like Zac Efron and Vanessa Hudgens and Russell Brand and Katy Perry only had eyes for each other. Natalie Portman stopped to say hi to her Black Swan costar Mila Kunis' boyfriend Macaulay Culkin, following his touching tribute to John Hughes. Lovely ladies like Kate Beckinsale and Anna Kendrick kept the fashionable times going, as the VF bash got a long night of partying in LA under way.
