Brooke Shields dons a white moustache in new 'got milk?' ad campaign

Actress Brooke Shields has become the latest celebrity to don a white moustache in the 'got milk?' ad campaign.

The sexy 42-year-old is encouraging Americans to boost their calcium intake by posing in nothing but a black polo neck sweater and matching panties. Her long naked limbs are curled underneath her body.

Hair flowing and back straight, Shields sits next to a caption that says: "Busy Body. Actress, model, mother, health nut, spokesperson, role model.

"How does a busy mom get it all done? I exercise, eat right and drink milk.

"Studies suggest the nutrients in three glasses of low fat or fat free milk a day can help maintain a healthy weight.

"Plus the protein helps build muscle for a lean body. Done."

The mother of two is the latest in a long line of celebrities who has encouraged Americans to add "milk" their "diet."

Previous 'got milk?' models have included singers Beyonc? Knowles, Rihanna and Sheryl Crow and football player David Beckham.

Shields stars in the US comedy drama, Lipstick Jungle, which is said to be the new Sex and the City.
