Many celebrities were a part of it, including Grammy Award winner Kelly Clarkson.

While singing her popular "Since You've Been Gone" on stage, Clarkson was joined by Shaq Diesel when the big man decided to jump on stage and join her.

Shaq is no stranger to musical events. Having released several rap albums of his own, Shaq has reminded us in recent years he loves being at a live show.

Never change Shaq.
