gotmilkadThe latest “got milk?” ad will debut on September 10th and features Hayden Panettiere.

Who knew? One of Heroes star Hayden Panettiere’s superpowers: lactose tolerant. The actress, who celebrated her 18th birthday on Tuesday with a party on the beach, is the latest mustachioed face of those “Got Milk?” ads.

“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.
