As previously reported, the New England Patriots quarterback, 38, returned to the field earlier this month after reportedly being aware of team staffers deflating footballs during the AFC Championship game in January. His suspension was overturned on Sept. 3 after he filed a lawsuit with the NFL Players Association.
Brady's personal life has also taken a couple of hits in the past several months. As exclusively revealed by Us, Bundchen, 35, threatened to divorce the athlete amid the sports scandal. (The couple are parents to son Benjamin, 5, and daughter Vivian, 2. Brady also shares son John, 8, with ex Bridget Moynahan.)
"Tom’s become very nasty and irritable and started acting out on her," an insider told Us. "Things are very tense right now. This could be the end of them."
Despite their marriage woes, Brady appeared in better spirits during an interview with Boston radio station WEEI on Sept. 8. "I’m a lucky man. I’ve been very blessed with support from my family and certainly her," he said at the time. "There’s no bigger supporter than I have than her and vise versa. I’ve been very blessed to have an incredible relationship with my life partner."
