Gisele Bundchen to Star in Steamy Calendar For Boyfriend

Gisele Bundchen's boyfriend will get a special surprise for his birthday in August -- the Brazilian beauty is planning to star in a steamy calendar just for him.

Bundchen, who is currently dating American football star Tom Brady, is set to pose in sexy lingerie and don a New England Patriots shirt to celebrate Tom turning 31 on August 3.

A source says, "Gisele wanted to do something special this year, so she is making a one-of-a-kind calendar for him.

"She has got some racy lingerie shots, a birthday cake shot for August, and the expected picture of her in knee socks and his jersey!"

Gisele, 28, has been discussing her ideas with several of her photographer friends and wants to shoot twelve different looks, which she plans to bind and present to Tom.

The source added to OK! magazine, "Tom has no idea about Gisele's plans, but he is going to love it!"

New England Patriots quarterback Tom recently revealed he fantasizes about Gisele dressing up as a superhero.

He said, "I want her to wear the Wonder Woman outfit."
