Grammy Awards 2009

Rihanna helped the Black Eyed Peas' will.i.am and Taboo start Grammy weekend off on a high note at the 5th annual Peapod Foundation concert, presented by Adobe Youth Voices. Once inside the Conga Room at L.A.'s Nokia Theatre, guests were treated to a performance by the Peas—with special appearances by Lupe Fiasco, Nikka Costa and Boys II Men—to benefit the foundation, which provides music and arts education to children around the world.
