MTV.com – It seems like a match made in pop-music heaven: Lady Gaga and Cyndi Lauper. The two flashy blondes aren’t collaborating musically, however: They’re appearing together in MAC’s new Viva Glam campaign and lending their names to new lipsticks that benefit the MAC AIDS fund.

The Viva Glam Cyndi and Viva Glam Gaga lipsticks will be available on March 18 and will retail for $14. This Wednesday both Gaga and Lauper will appear on “Good Morning America” and the “Today” show to promote the lipstick and the cause, according to MusicFascination.com.

The ladies also look appropriately glamorous in “From Our Lips” ads, which were shot by Ellen Von Unwerth and are set to appear in magazines later this month, Idolator.com reported. As Gaga and Lauper pose like adorable retro pinup girls, one ad reads, “You know you’ve got a sexy voice. Use it! Let’s talk about how to keep your love life safer, seductive and satisfying. Just between us girls!”

Gaga and Lauper join a list of famous singers who have worked on the Viva Glam campaign. Fergie, Christina Aguilera, Eve, Mary J. Blige and Lil’ Kim have all helped sell the lipstick line, which MAC started in 1994, donating every dollar of its sales to help men, women and children affected by HIV/AIDS.
