Following the Academy Awards on Sunday, Graydon Carter’s Vanity Fair after-party at the Sunset Tower Hotel was the place to be.

Arriving shortly after 11 p.m., Jennifer Aniston and fiancé Justin Theroux relaxed at the Tower Bar where a jazz combo performed.

Aniston chatted with Molly Sims but Theroux was never far. The couple was inseparable, smiling and laughing as the night went on. Aniston looked like she was having a ball and so happy in her red Valentino gown.

Posing for pictures with huge smiles on their faces, the duo seemed carefree.

Another couple, Catherine Zeta Jones and Michael Douglas arrived later, around 11:30 p.m. Sitting in a booth with Tim Burton and Helena Bonham Carter, both appeared very talkative – with Douglas standing a lot of the time to talk to some of the old timers. Several guests approached the actress to congratulate her on Chicago performance earlier in the evening.

Oscar winner Ben Affleck and wife Jennifer Garner also made a brief appearance before leaving to attend fellow Argo producer George Clooney‘s party.

Garner looked at her husband adoringly and let him have his celebratory night.

Heat costars Sandra Bullock and Melissa McCarthy hung out together in the bar area.

Quentin Tarantino was celebrating his win by speaking with Tim Burton and Adrien Brody about the very thing he won his Oscar for – his writing!

Reese Witherspoon and husband Jim Toth stayed close as they made their rounds, with Witherspoon being very chatty.
