Marsha Ambrosius and Natalie Stewart are the funky divas behind the neo-soul duo Floetry. Ambrosius and Stewart emerged in the mid-'90s as songwriters in demand. They're behind some of the new millennium's biggest hits, too. The pair has written tracks for Michael Jackson, Jill Scott, Glenn Lewis, and Bilal. While they're highly respected behind the scenes, Floetry is their way of moving up front.
