Kanye West Joins Prince Onstage
Rap superstar Kanye West joined musical legend Prince onstage during the Purple One's concert at Way Out West 2011 in Sweden. Prince was performing his classic 1987 tune "If I Was Your Girlfriend" when West came onstage.
Kanye led the crowd in a call-and-response and had the entire audience waving their hands.
Kanye has been promoting Watch the Throne, his collaborative album with Jay-Z, which hit stores last week.
