Friends of Bridget Moynahan are worried about the actress's weight loss in the weeks since her split from quarterback Tom Brady. "She's depressed," said a friend. "We were worried about her before, but she's just gotten too thin. It's unhealthy... She's spending all of her free time at the gym." The recent rumors that her ex has moved on with supermodel Gisele Bundchen are also taking their toll. "If Gisele Bundchen were dating your ex-boyfriend, wouldn't you be depressed, too?" says the friend. Moynahan's rep denies the reports, saying, "There has been no change in the actress's weight. She is happy and healthy."
