Kristen Stewart looked stunning on the Oscars red carpet last night and had Taylor Lautner's arm to help stay solid on her feet when she stepped out to present. As the evening rolled on, however, Kristen had to do what so many other women must have, too: she kicked off her high heels and went barefoot to the Vanity Fair afterparty! Kristen's dramatic train on her navy gown covered up her shoeless feet, while her beautiful updo remained perfect—find out how to get Kristen Stewart's Oscar hair here. She stuck with Taylor for much of the night, but also chatted with fellow actresses like Julianne Moore inside the party. O-day can be quite the marathon and Kristen ducked out before the party ended, slipping into the back of her awaiting car without, fingers crossed, stepping on anything sharp. 
The Governors Ball was the first stop for many of the winners and presenters after last night's Oscars ceremony. Best actress Sandra Bullock went from chatting about her award in the press room to the afterparty, where she shared a special moment with her supportive husband, Jesse James. Maggie Gyllenhaal didn't claim a statue for Crazy Heart, but she continued the family evening by joining her mother Naomi Foner for a bite. Barbara Streisand cuddled up to Gerard Butler, while Diane Kruger brought her Chanel gown from the red carpet to the ball. 
Oprah Winfrey joined Gabourey Sidibe after her touching introduction during the best supporting actress presentation. Zoe Saldana stayed in her voluminous dress—which turned out to be quite the trendsetter—, while Neil Patrick Harris relaxed with David Burtka after his amazing opening number. Sigourney Weaver was happy to let her hair down with Anna Kendrick despite Avatar's not winning Best Picture, but Kathryn Bigelow and screenwriter Mark Boal were thrilled their film The Hurt Locker took home the accolade. 
While the Vanity Fair Oscars afterparty was one hot ticket at LA's Sunset Towers, Elton John played host at his 18th annual AIDS Foundation bash at the Pacific Design Centre. Elton's fellow Brit Simon Cowell came out with his fiancee, Mezhgan Hussainy, and Victoria Beckham turned out to mingle with pal Heidi Klum. Nicole Richie struck a little pose with Rachel Zoe, while Glee's Lea Michele dug into the dinner and Salma Hayek arrived in her leather jacket. Gossip Girl's Chace Crawford chatted with the host as Jamie Foxx escorted his lady friend Stacey Dash. 
Jennifer Hudson made the social rounds in a blue gown, which turned out to be one of the big colours of the red carpet. Nicole and Joel Madden shared a moment after his turn as the show's official DJ, while the three Jonas brothers hung out nearby. Elton's glasses matched Betty White's own blue dress, as they celebrated her The Proposal costar Sandra Bullock's big win. Miley Cyrus took a break from boyfriend Liam Hemsworth to smile for photos with Joaquin Phoenix as the fun times continued at one of the biggest bashes of the year. 
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.
