Carrie Underwood gets a Milk Mustache

During the past decade, the Milk Mustache campaign has helped curb the country's calcium deficit and educate Americans on the many reasons to drink milk - from reducing the risk of osteoporosis to helping maintain a healthy weight. This month the campaign will be launching a new program, Body By Milk, to educate teens about the benefits of drinking milk from how it can help them keep a healthy weight and how milk helps build more muscle.

The previous list of celebrities who have participated in the Milk Mustache campaigns include Mischa Barton, Freddy Adu, Elizabeth Hurley, Sheryl Crow, Ben Roethlisberger, Joss Stone, Kelly Clarkson, Batman, Donovan McNabb, Andy Roddick, Hilary Duff, Bernie Mac, Superman, Britney Spears, Kim Cattrall, Jessica Alba, Angelina Jolie and Lindsay Lohan.
