Hayden Panettiere Shows off Her Pantie-eres—and Her Nipple!

Heroes Hottie Hayden Panettiere Proves She's a True Hero by Flashing Whale Tail and a Hint of Nip

On a recent shopping outing, perky pixie Hayden Panettiere gave her adoring public a hint of thong and bra beneath a see-through shirt. And while a backside see-through may not excite your own Peter Petrelli, Hayden had nakeder, fleshier tricks up her sleeve—she slipped her very first nip to celebrate her nineteenth birthday.

Hopefully Hayden will make this an annual event. She can reveal a new body part to celebrate each passing year. For her twentieth, the flashing of rear!
