Klum's ad, which will appear in People magazine's June 20 issue, features her getting camera-ready, and encourages fans to go to the campaign's Facebook page to see how milk can help people look and feel their best. She first appeared in a "Got Milk?" ad in 2008.

O'Neal's latest ad highlights dunking - but not the basketball kind. It shows him and his mother, Lucille, with a glass of milk and an Oreo cookie.

Other stars who have donned the 'stache include Lauren Conrad, Taylor Swift, Rihanna, Hugh Jackman (as Wolverine), Chris Bosh and Jennifer Hudson.
