Chris Brown joined Usher on stage during the Reggae SumFest 2010 in Montego Bay, Jamaica. The duo wowed audiences in the concluding night of the festival.

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.
