Killing the crowd with his Bruce Jenner comedy sketch was not the only act we saw this guy in during the Sunday night airing. Jamie Foxx & Chris Brown perform “You Changed Me” during the annual iHeartRadio Music Awards ceremony. The ballet, which will appear on Jamie’s new album (scheduled to release May 19), was performed with the piano as assistance and Chris Brown’s ill dance moves.
