Rihanna is denying that she made a sex tape with rapper J. Cole, despite Hustler‘s claims to be in possession of such a tape. J. Cole was the opening act for her recent tour. Hustler said in a statement: “Hustler are in possession of the Rihanna and J-Cole tape. We have seen it and we do not know what we are going to do with it yet.” That prompted Rihanna to tweet: “We don’t believe U, U need more people…AND of course an actual sextape! #slownewsday.” As pictured at left, Rihanna is currently cruising the Mediterranean on a yacht with a group of her girlfriends.
