We can't front like we're not still going through the withdrawal symptoms of Rihanna's abrupt departure from Instagram this spring. So quite naturally, we were geeked when pictures of her latest M.A.C. Cosmetics Viva Glam campaign popped up in our IG timeline this afternoon. Rocking a slime green wig with a matching two crop top and skirt, RiRi introduced the latest colors of her ongoing collaboration with the cosmetics juggernaut. In addition to her previous super shiny red Rihanna 1 lipstick and lip glass, this new collection offers a sparkly purple lip glass and a frosty mauve lipstick—we suspect that it's the very same color that RiRi wore last year when she was running around with grey hair. As is the case with all of M.A.C.'s VIVA Glam cosmetics, every cent of the sales goes toward helping women, men and children living with and affected by HIV AIDS. Check out pictures of the new colors below, preorder them here and prepare to see many a frosty gray-ish lips in your IG timeline this September as this collection is guaranteed to sell out.
