Not everyone can pull off being seductive in a sweatshirt, but Heidi Klum proved that she's not everyone in a new public service announcement for Stand Up to Cancer.
"If you don't want to be out, you can be in by joining me and the Stand Up to Cancer movement in the fight against cancer," said Heidi. "Let's all say Auf Wiedersehen (German for "goodbye") to cancer together!"
Heidi's "It's Up2 All of Us to Stand Up to Cancer" PSA will debut in People's "World's Most Beautiful" issue, on stands April 15.
Stand Up to Cancer is a charity organization focused on collaborating with investigators all over the world researching innovative cancer therapy as well as preventative medicine.
