Jennifer Lawrence Wearing Gray on Tonight Show | Pictures

Last night Jennifer Lawrence slipped into a body-hugging gray dress by Alexander Wang for an appearance on The Tonight Show. She chatted with host Jay Leno about her latest release, Silver Linings Playbook, which is out tomorrow, and shared a funny story about her obsession with Honey Boo Boo.

Later in the evening, Jennifer changed into a black Christian Dior number for the LA premiere of Silver Linings Playbook. There, she met up with costar Bradley Cooper and posed for photos with the entire cast. Early reviews praise Jennifer and Bradley for their onscreen chemistry and Hollywood insiders are already buzzing about possible Oscar nods for both actors.
