Kanye West is slowly but surely making his way back into the public eye. The Louis Vuitton Don popped up during Jay-Z's set at the Isle of Wight Festival in the UK over the weekend.

"Ladies and gentlemen, make some noise," Jay instructed the audience. "Mr. West is in the building!" Following the track West threw up the Roc, and quickly left the stage. To the complete surprise of the audience, West hit the stage to do his verse on 'Run This Town,' alongside Jay.

Jay headlined the three-day festival kicking off Friday (June 11). Other big names featured at the event included Paul McCartney, Blondie and The Strokes. The annual concert was first held in 1968 and has since become one of the area's popular music events, winning the Best Major Festival award at the UK Festival Awards in 2007.
