Joe Jonas' rep denies sex tape

Website blindgossip.com reported that the clean-cut Jonas Brothers star, who once wore a purity ring as a symbol of abstinence, was filmed engaging in explicit sex acts, drinking and smoking marijuana with the Swiss-born model.

The website also alleged that the video would be released next month (Apr13).

But a representative for the 23-year-old has spoken out to defend the star's squeaky-clean image, telling Us Weekly, "There is no truth or validity to the story. It is completely false."

The star also took to his Twitter.com page to address the rumors, writing, "ball gag? (sex toy) really? me? come on guys."

Jonas and Eggenschwiler started dating last year (12). The singer has previously romanced Twilight star Ashley Greene and Taylor Swift.
