What do Miley Cyrus, Yasmine Bleeth and Austin Powers have in common? Well, besides the fact that they all enjoy exposing themselves, they have all appeared in ‘Got Milk’ ads. And now, Demi Lovato is joining the ranks as well (but hopefully she doesn’t enjoy exposing herself quite so much as the other examples).

Demi recently shot her ‘Got Milk’ ad to encourage the consumption of milk as a healthy and nutritious part of a balanced diet (oh God, I sound like a cereal commercial). Says Demi, “On stage I get my energy from my fans. Off stage I dive into a glass of lowfat milk. The protein and other nutrients keep me rocking. Here we go again!”

Demi’s appearance in the ad is part of the ‘Body by Milk’ campaign, which specifically encourages young people to consume the popular beverage. The ‘Got Milk’ campaign is not without its controversy however. Animal rights groups like PETA and the Physicians Committee for Responsible Medicine have criticized the ads for misleading the public, arguing that dairy products are detrimental to people’s health.

Still, you have to love Demi Lovato crowd-surfing with a milk moustache. It sure is better than having to watch that White Gold clown.
