Angie Harmon was all smiles today (October 13) as she unveils her new Milk Mustache ad and celebrated chocolate milk as ‘The Official Drink of Halloween’ on New York Street in Paramount Studios in Los Angeles.

Joined by her three daughters in the ad, the 37-year-old actress strikes a casual pose while clutching on to a glass of the cold white stuff.

“At Halloween and throughout the year, my girls love the flavor of chocolate milk, and I love knowing it contains the same essential nutrients as white milk like calcium, vitamin D and other nutrients kids need to build strong bones,” says Angie. “As a mom, it’s important to me that my kids learn healthy habits early — and drinking three glasses of lowfat or fat free milk each day is one of the best habits I can pass on to them.”

Angie’s ad will debut in People magazine on October 16. The ad copy reads, “Angie’s Harmony. Welcome to my life. Sure I see it as a glass half full but it’s still a lot to handle. How do I stay balanced? Milk. It’s nature’s wellness drink — naturally nutrient rich like no other beverage. Now can someone just get me a straw?”
