Aniston joined Jason Bateman, Dax Shepard and Kristen Bell on Saturday night as they celebrated the birthday for Jimmy Kimmel's wife. Jimmy and Molly have been close friends with Aniston and Justin for years, and they even went on couple's vacations together.
Aniston looked drop-dead gorgeous in a black silk dress, and posed for pictures with Molly, Tobey Maguire's ex-wife Jennifer Meyer and Bateman's wife Amanda Anka.
Kristen Bell also shared an adorable video of the "Jimmy Kimmel Live!" host and his wife dancing to 50 Cents' "It's Your Birthday" during the cake presentation.
