Lil' Kim and Cyndi Lauper are bringing the flavor to Nelson Mandela's 91st birthday celebration. The not-so-unlikely pair will take the stage together to help honor the former South African president at Mandela Day: a 46664 Celebration, which will take place on July 18 at New York's Radio City Music Hall.

Other Mandela pairings include performances by Will.i.am with Jesse McCartney, and Alicia Keys alongside Angelique Kidjo. Stevie Wonder, T-Pain, Queen Latifah, Wyclef Jean, Gloria Gaynor and the Soweto Gospel Choir are also set to take the stage.
