Brady and Gisele - Engaged!!!

Tom Brady proposed to Gisele on a private jet on XMAS eve -- and she said yes.

Our sources say Brady, who is famous for his QB skills and running errands for Gisele, proposed on a private jet that took off from Teterboro Airport in New Jersey and landed in Boston. There were four dozen white roses on board, as well as champagne.

Along with Brady and Gisele were her parents. We're told Brady was nervous before he popped the Q.
