After months of speculation that their marriage is on the rocks, Gisele Bündchen allegedly threatened to divorce her husband, Tom Brady, after learning he was once flying high in a private jet with Ben Affleck’s former nanny and rumored mistress, Christine Ouzonian.

A source tells Us Weekly the 35-year-old model found out about the trip shortly after a picture of the former nanny, 28, wearing the 38-year-old quarterback’s Super Bowl rings surfaced online.
