The only other multiple winner was the hip-hop duo UGK, consisting of Bernard "Bun B" Freeman and the recently deceased Chad "Pimp C" Butler. In all 15 awards were handed out during a three-hour show mixing the heroes of contemporary hip-hop and old-school R&B.

Keys, flying high with a successful worldwide tour, a chart-topping album and an upcoming film, shared the stage with three leading female ensemble acts from the 1990s -- TLC, En Vogue and Sisters with Voices -- for a medley of R&B music.

She went on to win the prize for best female R&B artist, and offered a heartfelt endorsement to Obama, who would be the first African-American elected to the nation's highest office.

"Together we can do anything -- Obama, y'all!" she enthused.

Teen sensation Chris Brown, who topped the U.S. singles chart last year with "Kiss Kiss," was named best male R&B performer.

AL GREEN IS SORRY

The evening's most spine-tingling moment came when veteran soul crooner Al Green, recipient of a lifetime achievement award, got the audience in the Shrine Auditorium on its feet singing, and dancing, along with his classic 1970s hit "Let's Stay Together."

Backstage a short time later, Green apologized.
