Guess What Heidi Klum's Up To?

Heidi Klum is has often flaunted her perfect body (naked, too), but this weekend, she was spotted showing off her perfectly tousled curls as she filmed a commercial for a German hair spray from Schwarzkopf called Taft outside the Flatiron Building in New York.

Judging by the pics, we've learned that Klum's curls are wind-resistant, getting-caught-in-revolving-door-proof, and generally pretty bouncy and envy-inducing.
