Hayden Panettiere Lice Commercial

Heroes hottie Hayden Panettiere is of legal age, turning 18 today! HAPPY BIRTHDAY, HAYDEN!

Last night, during The Late Show with David Letterman, Hayden‘s childhood Nix lice commercial was aired. She’s the girl who “didn’t have lice.” Watch the video below (timestamp 2:40)!

The Heroes DVD is out next Tuesday, August 28! All-new episodes of Heroes returns Monday, Sept 24.

Just three minutes into her 18th birthday, a surprised-looking Hayden (yellow sweatshirt) was greeted by fans with bouquets of flowers at LAX airport. The first thing she wanted to do after turning legal… “buy porn and cigarettes!” (Yes, she was joking.)

10+ pictures inside of former Nix lice spokesperson Hayden Panettiere! Hayden wore a sequined Alice + Olivia dress with Steve Madden shoes.
