While Kanye West is surely busy with promoting his collaborative album with Jay-Z, Watch the Throne, it appears as though the Hip Hop star does have time to work with other music legends.

'Ye came on during the Purple One's performance of "If I Was Your Girlfriend." West's performance was essentially call-and-response, as the rapper got the crowd to wave their hands from side-to-side, and repeat several classic Hip Hop phrases.
