Celebrities at SAG Awards Afterparty at Chateau Marmont

Ben Affleck celebrated his big win at last night's SAG Awards with his wife, Jennifer Garner, and several other celebrities at Chateau Marmont in LA. The couple was spotted leaving after a bash with Hugh Jackman while still wearing their glamorous red-carpet looks, but not carrying Ben's award for Argo's outstanding performance by an ensemble cast. Amanda Seyfried, though, changed out of her blue Zac Posen gown into a sheer black cocktail dress. Amanda's Les Misérables costars Anne Hathaway, Eddie Redmayne, and Hugh Jackman also attended festivities at the Chateau along with Homeland's Damian Lewis.

Ben and Jennifer appeared to enjoy themselves at the actual SAG Awards, where they were seen laughing and acting affectionate throughout the show. Earlier yesterday, Ben took his daughters, Violet and Seraphina, to a farmers market in Brentwood to pick up some fruit and flowers. In addition to the SAGs and running errands, Ben also picked up the Modern Master honor from the Santa Barbara International Film Festival Friday and the best picture award from the Producers Guild Awards on Saturday.
