No. 9. Rye Rye

Birthdate: Nov. 25, 1990 (age 20)

Why She's Hot: When M.I.A. cosigns on you, you know you're doing something right. Explosive, street-style Baltimore rapper/dancer Rye Rye is already earning her keep with not only major buzz, but big name assists: her infectious 2010 single "Sunshine" featured the aforementioned M.I.A., while "Never Will Be Mine" (which recently hit No. 12 on the Club Play Chart) features Swedish Robyn. Both songs will be featured on "Go! Pop! Bang!," Rye Rye's highly anticipated debut album which will finally surface this fall after years of delay. The album will drop via M.I.A.'s Interscope imprint, N.E.E.T. Recordings.

NEXT: Nick Jonas
