LOS ANGELES -- It was an emotional night at the BET awards in Los Angeles as Chris Brown broke down in tears while paying tribute to Michael Jackson on the first anniversary of the King of Pop's death.

Brown has kept a low profile since he pleaded guilty to felony assault for beating up his former girlfriend, Rihanna in February 2009. But, he took center stage Sunday night peforming Jackson's signature dance moves with almost eerie accuracy.

Introduced by Jermaine Jackson, Brown embodied the King of Pop, wearing his fedora and spangled glove while moonwalking across the stage to "Billie Jean."

Brown broke down in tears as he grabbed a microphone to sing "Man in the Mirror." His voice cracked, he couldn't sing, and at one point he crumpled to the stage in apparent agony.


The 21-year-old returned to the stage later to apologize to his fans.

"I let you all down before, but I won't do it again. I promise you," Brown said.
