Lady GaGa and Cyndi Lauper strike a saucy pose together in this eye-catching new ad for make up brand MAC.

Looking like the Girls Just Wanna Have Fun star's younger but equally racy twin, GaGa playfully helps Lauper with her lipstick application in the burlesque-inspired campaign.

The bleached blonde singers are the new faces of MAC's Viva Glam Spring 2010 range, which is set to debut in February.
