Rihanna pulled the ultimate prank on U.S. funnyman and chat show host Jimmy Kimmel to kickstart April Fools' Day early on Wednesday (01Apr15) - she crept into his Los Angeles home with members of her entourage while he was sleeping and performed a 1am alarm call, complete with flashing disco lights. The footage will appear on Kimmel's show, Jimmy Kimmel Live, on Wednesday night.
