Nicki Minaj is puckering up for a good cause. The “Super Bass” rapper has been announced as the newest spokeswoman for the M.A.C AIDS Fund VIVA GLAM initiative.

The Harajuku Barbie will star along with Latin superstar Ricky Martin in the cosmetics company’s 2012 campaign, set to launch in February. All sales from VIVA GLAM lip products will benefit the fight against HIV/AIDS.

Famed photographer David LaChapelle is shooting the ads with the duo today in Miami. “Viva Glam Photo Shoot. Ur gonna GAG!!!!!” wrote an excited Nicki. “Can’t wait for my barbz & ken barbz to wear this new shade of lipstick! Wait til u see it! Sickening!!!!”

Minaj follows past VIVA GLAM spokesmodels including Lady Gaga, Lil’ Kim, Missy Elliott, Eve, Mary J. Blige, Christina Aguilera, and Fergie. The fund has raised $224 million to date.

This is not the first time the two have worked together. Last year, the Young Money raptress teamed up with M.A.C to release a limited edition “Pink 4 Friday” lipstick.
