Los Angeles - Ricky Martin and Nicki Minaj have been named the new faces of MAC's Viva Glam lipstick.
The unlikely pairing will have their own brands of lipstick - the Viva Glam Ricky and the Viva Glam Nicki - available through the range, all profits from which go to help fighting HIV and Aids.
The pop stars take over as the faces of the campaign from current spokesperson, Lady Gaga and will be shot for a campaign in Miami by fashion photographer, David La Chapelle.
Nicki tweeted: "Viva Glam Photo Shoot. Ur gonna GAG!!!!! Can't wait for my barbz & ken barbz to wear this new shade of lipstick! Wait til u see it! Sickening!!!! (sic)" Lipstick for Ricky
It is not known if Ricky will wear his brand for the shoot.
Nicki has previously collaborated with MAC on their Pink 4 Friday
lip shade, named after her debut album, Pink Friday
, which was launched last year. It proved to be a huge bestseller, and the $14 lipstick now fetches up to $88 on internet auction sites such as eBay.
Previous VIVA GLAM spokesmodels include Lady Gaga
, Lil' Kim, Missy Elliott, Eve, Mary J. Blige, Christina Aguilera, and Fergie.
