Joe Jonas' clean-cut reputation lives on. Despite a report claiming that the 23-year-old singer made a sex tape with his girlfriend, Blanda Eggenschwiler, a rep for Jonas tells Us Weekly that no such tape exists.

"There is no truth or validity to the story. It is completely false," the rep tells Us.

Blind Gossip reported Thursday, March 21, that Jonas -- once famous for wearing a purity ring -- filmed himself and Eggenschwiler, 28, performing explicit sex acts, drinking, and smoking pot. But his rep denies that the two participated in any such activity.

Jonas and Eggenschwiler, a Swiss-born model and graphic artist, were first spotted together last November. He was previously involved with Twilight star Ashley Greene and country sweetheart Taylor Swift, whom he infamously dumped during a 27-second phone call.
