Sofia Vergara and her son Manolo, 19, don milk mustaches in a new 'Got Milk?' ad.
The ad copy reads, "Family favorite. I love being a mom and doing what it takes to build a strong,
modern family--like serving my little boy milk. It has nutrients like protein and potassium that have helped him become, well, not so little."
Sofia, 38, showed off her bikini body in a Twitpic over the summer.
