Brown had already performed his own set on Friday, tearing through songs like "Run It" and "Forever" and showing off his formidable dancing skills. But it was his surprise appearance during Usher's set the following day that really set the crowd off. According to TheChrisBrownBlog.com, the two were also joined onstage by Elephant Man and later engaged in a dance-off.
Video footage from the performance had not surfaced online at press time, but photos reveal the two singing together and even showing some affection with an onstage hug.
Brown took to Twitter Saturday to thank Jamaica. "I wanna thank you Jamaica for your wonderful embrace last night at the show," he wrote. "Next time well do passa passa ... lmao ... (oh hell naw). Love ya!"
Later on Saturday, he tweeted about performing with Usher. "Me and Usher killin Jamaica right now," he wrote.
When Chris burst on the music scene five years ago, he was overcome with excitement when meeting Usher. "To see him face-to-face, I was like, 'OK, Chris, it's gonna be all right, just chill out right quick. You about to do the song, man, don't be no punk,' " Brown told MTV News about recording a song that was later featured in Usher's 2005 film "In the Mix."
