Calvin Harris was one of the big acts at last weekend's T in the Park festival. And even though he's a superstar DJ, Calvin had a trick up his sleeve to prevent him being outshone by other big acts like Rudimental and the Arctic Monkeys. His name? Will Smith.

Yes, Calvin drafted/helicoptered THE FRESH PRINCE in to accompany him on stage during a rendition of mega-hit Summer - a decision that was presumably made when they were hanging out at the Chateau Marmont in LA or something.

It was kind of random, but also brilliant - Will Smith just sort of stands there and dances, while Calvin asks everyone "to give a very Scottish welcome" to the actor. We may never know why he didn't rap Fresh Prince of Bel Air alongside Harris - or do the Carlton Dance, but we did enjoy this T in the Park moment.
