Gisele Bündchen is "sincerely happy" for ex-husband Tom Brady following his Wednesday announcement that he has decided to retire from football, but has reportedly "moved on" with her life. "Gisele moved on with her life quite a while ago and is happy about whatever Tom chooses to do with his life now," a source close to the supermodel told People magazine, adding that "the welfare and happiness of the children" is what is most important to her.
