Heroes "Got Milk"

HEROES star HAYDEN PANETTIERE is celebrating her 18th birthday as the latest face of America's iconic 'Got Milk?' advertising campaign.

The sexy blonde turned 18 on Tuesday (21Aug07) and will appear in new print ads, shot by celebrated photographer Annie Leibovitz.

The actress' campaign, which begins next month (10Sep07), is aimed at urging teenagers to drink three glasses of low-fat or fat-free milk a day.

Panettiere will sport the famous milk moustache, wearing a red dress, in the new ads. Head over to ENI and check it out.
