Award-winning singer/songwriter Miranda Lambert stays in harmony every day by eating a good breakfast that includes plenty of low-fat milk. She also sports a Milk Mustache in the National Milk Mustache "got milk?®" Campaign ad unveiled last week at the Country Music Association in Nashville, Tenn.

The ad launched along with the 46^th annual Country Music Awards, where Lambert took top honors as female vocalist of the year for the second straight year. She also earned the song of the year award for "Over You." 

Lambert recently made music history when her latest album, "Four The Record," debuted atop the Billboard Top Country Albums Chart, making her the first artist to have each of her albums debut at number one.

The new ad showcases Lambert's cool country style and her favorite way to start the day: having a tall glass of milk and a bowl of cereal while strumming her guitar. The ad copy reads "Fine tune your morning. got milk? Nourish every day."
