Model Gisele Bundchen is not going to wed her football star boyfriend Tom Brady, according to his father.The supermodel reportedly got engaged to Brady following his proposal on a private jet that took off from Teterboro Airport in New Jersey and landed in Boston, Massachusetts on Wednesday. Brady packed the plane with four dozen white roses and champagne for the happy event, reportedly witnessed by Bundchen’s parents who were also on board the plane, according to TMZ. But Brady’s dad, also called Tom, is slamming the report, and is insisting he hasn’t been told of any engagement. He tells America’s The Boston Globe newspaper, "(Engagement story is) rumor, rumor, rumor… We don’t know a thing about it. Nobody told me. We talked to him and there’s nothing to say." Bundchen’s twin sister also dismissed the report, telling journalists the story is "not true".A representative for Brady’s football team, the New England Patriots, tells People.com, "I heard the report that he (proposed) on a plane, but I don’t think it’s true."Tom keeps his private life private." The couple have been dating since 2006.
