We know Hayden Panettiere is 18 now.
But, still, the Heroes actress shouldn’t go flaunting her goods everywhere she goes.
Seen here during the show’s worldwide tour, Milo Ventimiglia is trying to warn Panettiere that a certain body part of hers may be exposed. We hope she listened…

Pity Greg Grunberg in this scenario, people.
He’s just trying to have a good time with his Heroes cast mates… but it gets dangerous when you’re over the age of 30 (or 21) and dancing this close to Hayden Panettiere. Even though the beautiful young actress is celebrating her 18th birthday soon, well, she’ll still just be 18.
So we wish you luck, Greg. You can always think about baseball or something…
