All proceeds from the Viva Glam products benefit those affected by HIV/AIDS

In addition to prepping a pair of albums for 2014, Rihanna is continuing to beef up her fashion and beauty presence with a new ad campaign for MAC Cosmetics’ Viva Glam. This latest venture follows behind her deal as the new face of Balmain.

In nothing more than a blond bob and red lip, the 25-year-old star is stripped down and looking hot in the Inez and Vinoodh-shot photo. But don't worry, all that skin is for a great cause.

"#MACgirlz my new #VIVAGLAM lipstick AD CAMPAIGN is out now!" Rihanna tweeted Friday. "Every penny you spend on my #VIVAGLAM lipstick goes to the @maccosmetics MAC AIDS Fund to support people directly affected by HIV/AIDS!"

The singer has been in good standing with MAC Cosmetics for quite some time, releasing several collections for the beauty brand.

Rihanna joins past Viva Glam spokeswomen such as Nicki Minaj, Lil Kim, Lady Gaga, Missy Elliott and others.
