NFL star Tom Brady and his leading lady, supermodel Gisele Bundchen, have made it official -- the unbelievably attractive couple is engaged to be married. Brady proposed aboard a private jet on Christmas Eve, accompanied by four dozen white roses, champagne and Bundchen's parents who were visiting from Brazil. Could they be any cuter?

Here at That's Fit, we're fans of both Tom and Gisele already -- they're both so fit and healthy (and dreamy, of course). While Brady's athletic prowess is well-documented -- he is one of the best quarterbacks playing professional football, after all -- Bundchen's should be noted as well. She originally wanted to become a professional volleyball player in Brazil, and with her height and work ethic, she might've had a shot. You know, if the whole "highest earning supermodel" thing hadn't gotten in the way.

Now, I'm not normally one to push a couple to have babies -- not by a long shot. However, I cannot wait to see how athletic their kids are going to be. I bet Gatorade, Nike and Oakley are already setting aside funds to scoop up Baby Bundchen-Brady's endorsement!

Update: The couple's families are denying the engagement. However, a spokesperson for Tom's team, the Patriots, says that while he doesn't think the engagement rumors are true, "Tom keeps his private life private." I'm still holding out hope for their genetically gifted offspring debuting soon!
