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.
