Hayden Panettiere's milk ad

Hayden Panettiere will be appearing in an upcoming “Got Milk?” advertisement. People Magazine provided these details about the ad:

‘You don’t have to be a hero to feel invincible. That’s why I drink milk,’ she says in the ads, part of a campaign to get teens to drink three glasses of low-fat or fat-free milk a day. The ads, debuting Sept. 10, were shot in May by famed photographer Annie Leibovitz and show Panettiere in a sleek red dress holding an exploding glass of milk.
