Lady Gaga is all glammed up for her new ad with Cyndi Lauper for MAC's Viva Glam Spring 2010 campaign, to debut in February. Each songstress will tout her own new shade of lipstick, Viva Glam Gaga and Viva Glam Cyndi. The product won't hit stores until March 18, so you'll have to wait until then to have Gaga lip color.
Gaga and Lauper are the newest faces of the MAC AIDS fund, which has raised over $150 million since 1994. Previous spokesmodels include Fergie, Pamela Anderson, Christina Aquilera, Missy Elliot and Chole Sevigny.
