Miranda Lambert looks sizzling hot and country cool with a white mustache, ripped jeans, cowboy boots and a guitar on her lap for the newest Got Milk? advertisement.  The backdrop of the photo features vast green fields of grass as Lambert sits against a wooden porch of a house.

The country superstar is excited to be a part of the American Dairy Council Got Milk? campaign.  

"I've seen the milk moustache campaign forever. It's cool to join something that's very natural. It joins all kinds of genres together, and all kinds of entertainers together," she said to CountryWeekly.com.

She joins other celebrities including Hugh Jackman, Jennifer Hudson, Hiedi Klum and more to wear the signature white milk mustache.
