Bradley Cooper and Jennifer Lawrence Silver Linings Playbook

Jennifer Lawrence stepped out in a short Christian Dior dress for her Silver Linings Playbook premiere in LA last night. She was joined on the red carpet by a Gucci-clad Bradley Cooper. The costars have been spending a lot of time together promoting the film. Over the weekend, Jen and Bradley linked up for a special SAG screening of the film, which was out in limited release Friday and will be out more broadly across the country tomorrow.

Also in attendance for last night's premiere was Jennifer and Bradley's costar Chris Tucker and director David O. Russell. Chris told us all about making the film and touched on the amazing rapport between Jennifer and Bradley. He said, "It was great because they had so much good chemistry . . . David O. Russell is a great director. He had a great cast with Jennifer, Bradley, and Robert De Niro, and Jacki Weaver."
