Gisele Bundchen and Tom BradyGisele Bundchen's body is set to undergo a major transformation.

The sexy supermodel's famed for having a bod to die for.

But all that's about to change... for the best of reasons.

Because her husband Tom Brady has officially announced she's pregnant.

Putting an end to months of speculation, Gisele's America football-player hubby confirmed the news in a TV interview on sports channel ESPN yesterday.

Revealing that they're expecting their first child in December he joked: "It couldn't be harder than this training camp, so I'll be prepared."

The proud dad-to-be added: "The women are the ones who have to do the work, we just have to be there to support them and so it'll be nice to do that."

Congratulations, guys.
