Rihanna Strips Down for Mac Viva Glam Campaign

In true Rihanna style, the risqué singer bared it all for her latest MAC Viva Glam campaign.

The "Diamonds" singer posed for famed photographers Inez van Lamsweerde and Vinoodh Matadin, who also shot her recent Balmain campaign. 

Rihanna didn't shy away from showing excitement, posting on her Instagram: "#MACgirlz my new #VIVAGLAM lipstick AD CAMPAIGN is out now! Every penny you spend on my #VIVAGLAMlipstick goes to the @maccosmetics MAC AIDS Fund to support people directly affected by HIV/AIDS! To find out more go to MACcosmetics.com #StayTuned (shot by: @inezvinoodh)."

The pop star first announced her partnership with MAC last February and released her first lipstick that following May. She has since released a summer, fall and holiday collection with the makeup label. 

Rihanna's MAC Viva Glam lipstick and lipgloss will be available online in North American on Jan. 21 at maccosmetics.com and in stores Jan. 23.
