Brazilian supermodel Gisele Bundchen has stripped off for a sexy beach photo shoot amid reports she's pregnant with her second child.
Bundchen, 31, 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 she 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 $US45 million ($A44.55 million) in the past 12 months.
Bundchen and her husband, US professional footballer Tom Brady, have yet to comment on the pregnancy stories.
