Heidi Klum has posed nude -- all for a good cause, of course.
The foundation has a new tote bag for sale designed by Jean-Paul Gaultier to benefit AIDS research.
"Our longtime friend @HeidiKlum bears all for @amfar...to raise HIV/AIDS awareness," the foundation writes on Instagram.
The summery, nautical-inspired bag went on sale June 1 at Bloomingdale's, and 100 percent of the proceeds go to amfAR.
