InStyle's Academy Awards Viewing Party

Dianna Agron

(in J. Mendel) and Vanessa Hudgens (in Marchesa) were among the stars who cheered on their favorite Oscar nominees during InStyle's annual Academy Awards viewing party, held at L.A. hot spot Boa Sunset. "I'm always ready to dance. My life is like a big dance floor," said Hudgens, who kicked up her Sergio Rossi heels during commercial breaks. "Plus Sundays are my cheat day, so I'm very happy that there is a candy bar here!"

The party was the first stop of the night for Kim Kardashian, who also put in an appearance at the Elton John AIDS Foundation Oscar viewing party before heading home. "OK I know the night is just beginning but I snuck away and now I'm in bed," Kardashian (in J. Mendel) tweeted. "I have a big day ahead of me! I'm exhausted! Night night!"

While Jennifer Morrison (in a Fada dress and jewelry from the Gilan Heritage Collection) and Cobie Smulders (in Calvin Klein Collection) shared a laugh while watching Anne Hathaway and James Franco spoof the year's hottest movies, both actresses were serious when it came time to eat. "We're wearing white dresses so we had to nix the sliders when they came around," explained Smulders. Added Morrison, "We might end up wearing the mini burgers!"

Jenna Dewan

(Ronald Abdala) left husband Channing Tatum at home to have a girls' night out with best friend Emmanuelle Chriqui (in Max Azria). Dewan stood out in crimson, the color of the moment. "I'm intuitive," the actress joked when asked about her gown. "I said, 'Okay. I have to wear what Sandra Bullock is wearing!'"

After making his predictions for the Academy Awards ballot contest-the four guests who correctly guessed the most winners received diamonds from Forevermark-self-proclaimed "Oscars nut" Darren Criss (in Armani) held court in his own private corner of the party, where he kept one eye on the television and one on the buffet table. What was the Glee star's favorite moment of the ceremony? "Anne Hathaway, I adore Anne!" Criss said of the Oscar co-host, who will soon make a guest appearance on Glee. "I think she's wonderful."

"The best part about this dress is that I can eat as much as I want because it stretches," said Amber Heard of her sleek John Paul Gaultier jersey gown.

Looking lovely in Collette Dinnigan, Taryn Manning shared her pick for the night's best dressed Oscar attendee. "I thought Mila Kunis looked amazing," Manning said. "Her gown is lavender, it's low cut and she looks hot." Before heading home, Manning talked music with Cee Lo Green during an impromptu fireside chat.

Clad in a Calvin Klein tux, Australian actor Liam Hemsworth claimed he spent no time getting ready for Hollywood’s biggest night. "It takes me about a half hour to get ready. I jump in the shower, put my suit on and get in the car," Hemsworth explained of his two-step strategy. "These parties are always great because everyone has so much fun."
