Gisele Bundchen goes nude for Vogue

Gisele Bundchen has stripped off for a sexy beach photoshoot amid reports she's pregnant with her second child.

The runway stunner poses topless as she strikes an over-the-shoulder pose for the cover of French fashion bible Vogue, wearing nothing but a pair of black bikini bottoms, and the 31 year old takes it all off for a black and white shot inside the magazine.

She's pictured lying face down on the sand, completely naked.

The images emerge less than a month after Bundchen was named the highest paid model in the world by Forbes magazine, banking a whopping $45 million in the period from May, 2011 to May, 2012.

Gisele Bundchen and her husband, sportsman Tom Brady, have yet to comment on the pregnancy stories.
