Pals of Bridget Moynahan are worried that the model-turned-actress is risking her health with her recent weight loss.


"She's depressed," says 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 "Six Degrees" actress has been through a rough patch lately after the demise of her three-year relationship with New England Patriots quarterback Tom Brady. Reports in the Boston Herald that Gisele Bundchen was hanging outside his locker room within a month didn't help.


Says the pal: "If Gisele Bundchen were dating your ex-boyfriend, wouldn't you be depressed, too?"


Her rep told us yesterday: "There has been no change in the actress' weight. She is happy and healthy."
