Though nothing is confirmed just yet, Gisele Bundchen certainly looked to be sporting a baby bump on Sunday.

The Brazilian supermodel — wife of NFL star Tom Brady, 34 — seemed to have some very special cargo on board when she touched down solo at Santos Dumont Airport in Rio de Janeiro, Brazil.

Bundchen, 31, wore a loose fitting grey top, that seemed to accentuate her protruding tummy.

So what is Bundchen saying about her possible pregnancy?

The mother of two-year -old Benjamin is staying tight-lipped on the baby bump rumors, which is unusual considering her normally outspoken personality.

The wife of the New England Patriot’s quarterback infamously lashed out at fans after Brady lost this year’s Super Bowl.

Bundchen was criticized for slamming her husband’s team mates when she was heckled by fans at the game.

“You (have) to catch the ball when you’re supposed to catch the ball,” she was caught on video saying.

“My husband cannot f***in throw the ball and catch the ball at the same time. I can’t believe they dropped the ball so many times.”

Foul mouth rants aside, Bundchen and her football star hubby — who has another child from a previous relationship — have plenty of room to start a NFL team of their own, having moved into their giant Brentwood, Calif. mansion earlier this year.

The $20 million mansion is 22,000-square feet, boasting eight bedrooms — including a nursery — as well as a six-car garage and a lagoon-shaped swimming pool with spa.
