Although Kelis has been a huge sensation in Europe, Latin America and Asia since 1999, she didn't hit it big in America until she released her third album, Tasty, in 2003. Her single "Milkshake" had women everywhere shaking their booties, for which we are eternally grateful. Kelis has also collaborated with an incredible range of musicians, including Busta Rhymes, Foxy Brown, Lil' Kim, OutKast, Diddy, Usher, Moby, Bjork, No Doubt, Enrique Iglesias, and her husband, rapper Nas.
