Bradley Cooper and Zoe Saldana were joined by Bradley's mom, Gloria, and his dog, Charlotte, for a Thanksgiving Day walk in Malibu last week. Bradley and Zoe are back together after a brief split in the Spring, though they've kept a low profile since reuniting. The couple met up on the red carpet for The Words in September and later that month were spotted sharing a movie date. Lately, though, Bradley's been out and about with another leading lady, his Silver Linings Playbook costar Jennifer Lawrence. The duo premiered their film in NYC and LA and also showed it off at a special SAG screening earlier this month. Reviews of Silver Linings Playbook are strong, but it couldn't top the holiday box office against Breaking Dawn Part 2, Skyfall, or Lincoln.
