Bruno Mars brought his A-game dance moves to the Grammy Awards. But what is his dance secret? Michael Jackson had his diamond sharp upper body. Elvis had that pelvis. James Brown was always on the good foot.

His knees send him in every direction while his upper body stays as still and elegant as a ballet dancer. Click through to see the secrets of his movements and watch his performance of "That's What I Like" here and his tribute to Prince.
Look how far inward Bruno's knee can go — as compared to how far out his elbow goes in the opposite direction during this Prince tribute.
