And now, Joe Jonas is joining the hundreds of people doing Beyoncé's dance to "Single Ladies (Put A Ring On It)" on YouTube.
In a new clip posted Wednesday, Nick and Kevin Jonas urge their brother, who is crouching down and hiding behind them, to "do this for the fans." When they move out of the way, the music starts and Joe, in a black skin-tight cat suit and pumps, starts to move to his hips. But what would Beyoncé say? Maybe, "Keep practicing."
