A Joe Jonas sex tape? What Joe Jonas sex tape?

While rumors of a Joe Jonas sex tape circulated online Thursday, the singer’s rep came out with a firm denial that any such tape exists.

The notion of the 23-year-old starring in such a tape, especially the way this one has been described, would be particularly notable given his and his brothers’ chaste reputations. And Jonas’ personal denial resulted in a post we never expected to see on his Twitter feed.

“ball gag? really? me? come on guys,” Jonas wrote in the afternoon.

Unexpected words from a guy once widely known for his purity ring.

Blind Gossip said the alleged tape — “There is no truth or validity to the story. It is completely false,” his rep told several outlets — features Jonas and his girlfriend, 28-year-old Blanda Eggenschwiler, doing the nasty, complete with weed, booze and sex toys in a Buenos Aires hotel room.

According to the site, the tape that doesn’t exist is due out early next month.
