Ball Buster! Potty-Mouthed Gisele Bündchen Defends Tom Brady From Super Bowl Heckler

Brazilian bombshell fires back at fan, saying her husband cannot "f--king throw the ball and catch the ball at the same time"

Tsk, tsk, Gisele Bündchen: That's not model behavior!

Sure, the Brazilian supermodel showed her soft side yesterday by comforting hubby Tom Brady after the Patriots' Super Bowl loss.

But she also unleashed quite the potty mouth when a fan dared to heckle her fallen husband.

And it was all caught on video...

In this clip from TheInsider.com, Bündchen is seen leaving the VIP section at Lucas Oil Stadium following the Patriots' crushing 21-17 loss to the Giants.

As she walks down the hallway, a fan is heard loudly jeering the supermodel and Brady.

Bündchen then fires off this zinger when she gets to the elevator: "My husband cannot f--king throw the ball and catch the ball at the same time."

Bust out the claws!

At least the couple can hunker down and console themselves at their brand-spankin'-new $20 million McMansion in Brentwood.
