Rihanna has showed big interest in doing more than just music lately. During London Fashion Week she released her own clothing line for River Island, and now she teams up with MAC to create a make-up line called RiRi [Hearts] MAC. The first product will be a red lipstick called RRi Woo, that will be out for sale in May. Rihanna says she's really excited to work with the brand, and that she's always been a MAC fan. ''I've been using MAC on tour for such a long time it was a natural fit for me. I have always loved make-up, and I always said that if I do it, I want to do it with a credible brand.", she said about the release. We'll be in line to buy the products! (contactmusic)
