Music superstar Usher has lent his moves to new game, Dance Central 3, which was unveiled at the E3 conference.

The Microsoft Xbox 360 Kinect title features two of his songs, which Usher choreographed dance moves for as well as taking part in a motion capture shoot.

He unveiled the game at a press conference in Los Angeles and performed his latest single, Scream, for the world's press.

Speaking after the launch, Usher hinted at a big public event that could be on the way.

"Who knows there may be a flash mob, hint hint, that comes up," he said.
