InStyle's Oscar Viewing Party

Zooey and Emily Deschanel

Held at L.A. hot spot MyHouse, InStyle's annual Academy Awards viewing party was the first stop on Zooey and Emily Deschanel's Oscar after-party circuit. "We consulted a little bit," Zooey (in Elie Saab) said when asked about getting ready with sister Emily (in Herve Leroux). Over salad and sushi, the sisters admitted they'd missed most of the show, but vowed to watch it after all the celebrating was over. "At two in the morning when we get home we're going to have another viewing party and stay up until five to watch it all the way through," said Emily.

Kate Walsh

While the crowd turned their attention to the giant flat screens broadcasting the ceremony, the comfort food-laden buffets and the Benefit Cosmetics beauty lounge provided plenty of opportunities for momentary distraction. "I'm running late!" said Kate Walsh, who looked flawless in a Stella McCartney dress and Neil Lane jewelry. "I had to make sure everything was in the right place in this dress, but there was no drama. Tonight is about the Oscars-it's not about me!"

Jessica Stroup and Zachary Levi

"I thought Jessica Stroup looked quite nice," said Chuck star Zachary Levi, making sure that the 90210 beauty was well within earshot. "I love him!" Stroup-who chose a black and white ombre stripe Pamella Roland gown and diamond earrings from JudeFrances Jewelry for the occasion-declared, returning the compliment.

Mena Suvari and Christian Siriano

How would designer Christian Siriano (in Ben Sherman) describe the bachelor pad-inspired decor at MyHouse? "Fierce, fabulous and flawless," said the Project Runway winner. Siriano spent most of the evening perched next to new friend Mena Suvari, who arrived wearing one of his designs. "She was in New York for Fashion Week," Siriano explained. "We met and she took a piece amp#91;from my collectionamp#93; right before it even went on the runway!"

Jessica Lowndes

"It's been crazy running into old friends that I haven't seen in a long time," said 90210's Jessica Lowndes, who caught up with former Greek co-star Spencer Grammer in between award presentations. What must-haves was Lowndes (in Alice + Olivia) carrying to carry her through the late night? "I bring gum, a camera, lip gloss and a credit card with me," said the actress, who picked her Oscar favorites for a chance to win one of two Dior watches.

Maria Menounos

After finishing up her duties on the red carpet, Maria Menounos headed to MyHouse to watch the ceremony before heading back out to cover the after-parties. "I've never been so scared in my life," Menounos (in Randi Rahm) said of the process of picking an Oscar gown. "I had a black dress that actually looked exactly like Angelina amp#91;Jolie'samp#93;, ready and waiting, but I put this dress on and I loved it."

Kate Mara and Anthony Mackie

"I am such a nerd for the Oscars. Every year I get so excited for it and try and see every single movie," said Kate Mara, who talked shop with guests like Hurt Locker star Anthony Mackie (left). Aside from the films, Mara was also into the evening's fashion. "I'm wearing a piece from the 50's," said the flame-haired actress of her vintage ensemble.

Brittany Snow

"I pay really close attention to the show," said Brittany Snow (in Erin Fetherston), who loaded up a plate of sushi to snack on as she watched the ceremony. "The Oscars gets me really inspired. I'm such a sensitive person that I start crying no matter what is on the screen!"

Spencer Grammer and Jason Lewis

"I got here too late to fill out the ballot so I don't get to participate," said Jason Lewis, who plotted an alternative way to take home the prize being awarded to the guests with the most correct Oscar predictions. "I'm going to make friends with the Dior people and supercede the whole thing!" Lewis also made friends with Greek star Spencer Grammer (in Corinna & Foley).

Yvonne Strahovski

"It's been a very chill day. Today was sleep in, have a cup of tea," said Yvonne Strahovski (right), who headed for the spread of M&M's and other candy to conjure up some extra energy for cheering on the Oscar nominees and hitting a few bashes around town. The Chuck star chose a bright Escada dress and Hearts on Fire jewelry for her night of party hopping.

Regina King

"I've had a bit of everything-the short ribs, the yams with rosemary, the salads," said Regina King, who took a break from the action to head upstairs for a make-up touch-up in the Benefit Cosmetics beauty lounge. "And I indulged in some junk food too. The s'mores popcorn was out of this world!"

Perrey Reeves

Entourage

star Perrey Reeves' (wearing Reem Acra and David Yurman earrings) secret to avoiding stiletto pain all night? "I'm wearing the Cole Haan heels with the Nike air sole," she revealed. "They finally have a red carpet collection-so comfortable and they have a four-inch heel!"
