Actor/rapper Will Smith made a surprise appearance at Scotland's T In The Park music festival on Saturday night (12Jul14) by introducing Dj Calvin Harris.

The Men in Black star is no stranger to the music stage, but he stunned fans who were anticipating a closing set from native Scotsman Harris.

Before Harris entered, Smith walked out in front of the thousands in attendance to a roar of applause, and told them, "I said to Calvin Harris, I have two weeks free and I want an experience. Calvin said, 'Come home with me, come to Scotland... Ladies and gentlemen - Scotland's own Calvin Harris!"

Near the end of his gig, Harris told the revellers, "T in the Park, I brought Will Smith here so I could see a real Scottish reaction. I want to see you jump up and down for Will Smith!"

Smith took to the stage yet again, as Harris finished up his set and fireworks lit up the sky.

Smith and Harris have spent the past few days together - they hit the party scene in Ibiza, Spain, where Harris posted a photo of himself with the actor at Amnesia nightclub on his page on Wednesday (09Jul14).
