The fine folks at Hustler magazine claim they have a sex tape featuring [lastfm link_type="artist_info"]Rihanna[/lastfm] and rapper [lastfm link_type="artist_info"]J-Cole[/lastfm].

The company says, “Hustler [is] 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.”

There’s no word how they got it, but J-Cole opened for Rihanna on her Loud tour this year and he tweeted on Tuesday that his phone had been stolen.

A source close to Rihanna says, “Rihanna is surprised because there is no sex tape.”

Someone sent screen shots to MediaTakeOut.com, and employees who’ve seen them aren’t necessarily convinced they’re authentic. They say the photos show,  “a woman with fiery red hair (that resembled Rihanna) giving [oral favors] to a man resembling J-Cole.”

Rihanna issued a denial on Twitter last night:

We don't believe U, U need more people…AND ofcourse an actual sextape! #slownewsday—
Rihanna (@rihanna) August 24, 2011

Not sure what she means by, “U need more people.” Meanwhile, there’s been no word from J-Cole.
