Nicki Minaj and Ricky Martin, promoting Mac\'s Viva Glam lipsticks London - Arabstoday   Nicki Minaj and Ricky Martinare living la vida Viva Glam. A promo, shot by fashion photographer David LaChapelle, features the duo wearing a lot of hot pink and motorcycle chic for MAC cosmetic\'s charity 2012 campaign. And when Puerto-Rican booty-shaker, Ricky Martin, was chosen alongside lipstick loving rapper, Nicki Minaj, to become the new face of Mac Viva Glam 2012, the union caught attention because of its unlikelihood. The 28-year-old rap singer flaunts her best assets as she suggestively kneels on a motorbike, while Mr Martin, 39, does his best to keep up, flexing his tattooed biceps. The 28-year-old rapper and the 39-year-old Latin sensation became involved with the lipstick campaign, whose motto is: “Every cent of the selling price of MAC VIVA GLAM lipstick and lipglass is donated to the MAC AIDS fund.”“Barbz, check out my #MACVivaGlam photo w/@ricky_martin on Facebook! Lipstick’s out in Feb–buy 1 save a life!” Nicki tweeted about the good cause. Nicki and Ricky took over as faces for the campaign from former poster gal Lady Gaga. The two lipsticks, both shades of pink, are sold entirely for charity, with 100 per cent of the sale price of each product donated to help fight HIV and AIDS.
