The stars kept the party going after last night's Screen Actors Guild Awards at the Weinstein Company's bash held at Sunset Tower in LA. Mad Men's Christina Hendricks cuddled up to her husband, Geoffrey Arend, while her costar Jon Hamm posed for a picture with Glee's Chord Overstreet. Dianna Agron let loose with Helena Bonham Carter as Justin Timberlake partied alongside a pal nearby. The cast of Modern Family celebrated their big win, with Ty Burrell chatting up Matthew Morrison, as The King's Speech's Colin Firth mingled with his famous friends. Tobey Maguire and his wife Jennifer Meyer showed their support for all the evening's honorees, like best actress winner Julianna Margulies, who threw a happy arm around pal Kyra Sedgwick. Mila Kunis, meanwhile, raised a glass with her Black Swan director Darren Aronofsky.
