An insider tells People magazine that 29-year-old Tom and 26-year-old Gisele "started dating just before Christmas." They were first linked in the press earlier this month when Bundchen was seen waiting outside the Patriots locker room after the team played the San Diego Chargers. A source for the Boston Herald said, "She was standing outside the locker room, just kind of leaning against the wall. No one noticed her, she was dressed like a high-school kid, just in jeans and a T-shirt. But she is gorgeous." And a rep for the Chargers told People, "[Gisele] was in the stands. I'm 100 percent sure. [A Charger employee] saw her walking in concourse area."

Brady's romance with Bundchen is a rebound. He recently Brady broke up with his girlfriend of three years, actress Bridet Moynahan. Moynahan isn't taking the news of Brady's new love interest very well. A source told the New York Daily News, "She's depressed. 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…If Gisele Bundchen were dating your ex-boyfriend, wouldn't you be depressed, too?" Bridget's rep denied that the actress has been having any problems post break up, stating, "There has been no change in [Bridget's] weight. She is happy and healthy."

Perhaps Bridget had long suspected that something like this might happen. Gisele has been very open about her feelings for Tom in the past. Last month she told the Herald, "Tom Brady, definitely not too shabby. He's pretty cute. All-American, that's a good way to describe him." She denied that she would ever try to steal him away from Bridget, though. She said, "He's cute, but if he has a girlfriend, he's gay to me. There are too many men in the world to go after a man who has a woman. Life is too short."
