The Jimmy Kimmel Live studio couldn't hope to contain Prince, so when the rock great stopped by the show last night, he performed to a large, enthusiastic crowd on the outside stage. Dressed in orange-yellow pants and a wildly patterned shirt with impressive dangling tassels, Prince played his new single "Rock & Roll Love Affair" with absolute joy, sneaking in a few grins as he stomped through the funky, horn-blaring track. He calls it an affair, but almost 35 years after his first album, it might be a little more serious than that.
