Rihanna goes topless for MAC Viva Glam...

A blonde wigged Rihanna goes topless in her ad for MAC Cosmetics’ Viva Glam campaign, shot by Inez & Vinoodh. All sales from Viva Glam lip products will benefit women, men, and children living with HIV/AIDS. Rihanna's other deal with MAC involves her own line of cosmetics. Here, she's looking very foxy!
