Heidi Klum confessed she likes to sunbathe topless last night on The Tonight Show. The supermodel reminded us that she is European after all, explaining that she brings more bathing suit bottoms than tops on vacations — except when she comes to America. While Heidi once tried to go topless in Phoenix, hoping to avoid tan lines, she found herself in trouble. Jay Leno couldn't help himself, making sometimes uncomfortable jokes about Heidi's swimsuit preferences. But Heidi played along. Watch the two talk about uptight Americans, Seal in a Speedo, and more now.
