Anna Faris

Liam Hemsworth was joined by John Krasinksi, Taylor Lautner, and many more celebrities at Grey Goose's pre-Oscars bash at Chateau Marmont in West Hollywood last night. Liam went to the event without fiancée Miley Cyrus, who was busy attending a party for the Mario Testino exhibit at an LA gallery. Miley has had a busy weekend attending events and working on her new album. She tweeted earlier this weekend, "Making this record on top of Oscar weekend and all of fashion week is CRAY! Need a day of silence. Migraine. "

Other celebrity attendees at the Grey Goose event included Russell Brand, Jean Dujardin, and Parks and Recreation star Chris Pratt, whose film Zero Dark Thirty is up for several Oscars tonight, including best picture. Don't forget to join us for our LIVE Oscars red-carpet coverage starting at 5:30 p.m. EST / 2:30 p.m. PST.

Anna Faris stepped out with her baby son, Jack Pratt, in LA yesterday. She checked out a couple of stores and carried the 5-month-old as he slept soundly in his car seat. Anna is currently enjoying downtime on the West Coast between her big- and small-screen projects. She has a role in Movie 43 alongside stars like Halle Berry, Naomi Watts, and Hugh Jackman and is also gearing up for the release of the comedy I Give It a Year. Anna will be returning to TV, as well, playing a single mother in an upcoming CBS pilot, Mom, produced by Chuck Lorre.

Anna's husband, Chris Pratt, is also juggling his role as a new dad with his Hollywood duties. He took a break from filming Parks and Recreation to promote Zero Dark Thirty with Jessica Chastain and recently talked about being a "sterotypical soldier" on set.

Jessica Chastain wore a bold, blue Elie Saab dress to last night's LA premiere of her film Zero Dark Thirty. The actress stars as a CIA agent instrumental in the capture of Osama bin Laden in the thriller, which was directed by The Hurt Locker's Kathryn Bigelow. Jessica was joined by her costars, including new father Chris Pratt, who had his wife, Anna Faris, by his side for the debut of the true-to-life thriller. Guests including Aaron Paul and Alexander Skarsgard were also on hand to check out the critically acclaimed film.

We spoke to Jessica on the red carpet about her character Maya. She told us she wasn't able to meet the CIA agent the character is based on, because she is undercover, but spoke to the strong women both behind the camera and on the screen in Zero Dark Thirty. She said, "When you're on set with Kathryn Bigelow, you just think, 'This is one of the greatest directors I've ever worked with.' And that's it. Full stop. You don't think, 'And she's a woman!' She's just really good at her job, like Maya in the film is."

Over the weekend Anna Faris attended her first red carpet event since welcoming her son Jack in August. She joined her Parks and Recreation star husband Chris Pratt at Hollywood's Milk Studios for the second annual Reel Stories, Real Lives benefit, which raised proceeds for the Motion Picture & Television Fund. Anna and Chris had plenty of funny company during the gala, including director Jon Favreau, Russell Brand, Jon Hamm, and Armie Hammer. Jeremy Renner skipped the carpet, but he was inside later to speak on stage. We caught up with a handful of the stars before the proceedings began. Jon was tight-lipped about the action to come on Mad Men's sixth season, but he did confirm recent rumors about the plot involving Hawaii.

Anna Faris showed her baby bump in a tight green dress yesterday at the launch of the Samsung Galaxy S III in LA. After hitting the red carpet, she managed to catch up — and maybe get some parenting tips — from pal Ashlee Simpson. Ashlee had fun at the bash, tweeting that she loved the "gorgeous views" from the private residence and that the band "Alabama Shakes are rockin'!" Anna and her husband, Chris Pratt, are expecting their first baby later this year. They recently revealed that the coming bundle of joy will be a boy.

True Blood and Magic Mike hunk Joe Manganiello made the rounds as well, and even shared a photo of him having a great time with "b-girl" Anna Kendrick. Anna headed West after attending Tuesday's Coach party on the High Line in NYC. Chatting up Joe wasn't her only excitement last night — Anna also posted on Twitter, "Just tried Taco Bell's Doritos taco. I can see why they sold 100 million of these already. This is no joke." Other celebs like Dave and Odette Annable also checked out the bash, saying hello to his 666 Park Avenue costar Robert Buckley.
