Tom Brady and Gisele Bundchen are NOT Engaged

Rumors over Christmas claimed Tom Brady and Gisele Bundchen got engaged to be married. The rumor said Tom popped the question on a private plane in front of their parents who were onboard.

Brady’s father, Tom Brady Sr., told The Boston Globe on Friday that reports of his son’s engagement were "rumor, rumor, rumor … We don’t know a thing about it. Nobody told me. We talked to him and there’s nothing to say."

The Boston Herald reported that the couple strolled down Bean Town’s Beacon Street on Friday – and that Bündchen (28) was without an engagement ring.

Bündchen’s twin sister, Patricia, also denied the report, saying in an e-mail that the engagement story, which first surfaced on TMZ, is "not true."

Reached by PEOPLE, Bündchen’s rep declined to comment. Stacey James, a spokesman for the Patriots, responded, "I heard the report that he proposed on a plane, but I don’t think it’s true." Still, he added, "Tom keeps his private life private."
