Alt-R&B songstress Kelis has battled through label politics, the dissolution of her marriage to Nas, and a rollercoaster ride of album sales over the course of her career. Since the release of her debut LP in 1999, the singer has constantly surrounded herself with top-tier talent. Whether she's teaming up with Ol' Dirty Bastard on an ultra-funky rap cut, flexing her vocal muscles during one of her numerous collaborations with the Neptunes, or ruling over the dance floor with one of her later career electro-pop jams, Kelis never fails to make her presence known.
