Demi Lovato made a sex tape?

Demi Lovato’s rep is blasting reports that a sex tape featuring Demi - currently in rehab battling an alleged cocaine addiction -- is about to hit the internets. She told TMZ:

"Perpetrating these completely unfounded rumors from supposed sources while Demi is in treatment dealing with serious physical and emotional issues is disgusting. The sourcing on this report is so spotty that it is hard to fully respond."

As for claims that Demi's uncle, Francisco Lovato, kept people out of her tour while she had sex inside, Lovato's rep bristles, "Francisco Lovato is the brother of Demi's estranged father. He never traveled on the tour, and certainly didn't serve as some sort of chaperone. We would ask serious news outlets to strongly consider the source of this story before they regurgitate it."

Has anyone’s reputation and public perception changed more in the past six months than Demi Lovato? In June, she was just another boring Disney tween star who you wouldn’t give two thoughts about if you passed on the street. Now she’s a coke-snorting party girl who will punch you in the face in the afternoon and then film herself blowing your boyfriend in the evening. From this day forward, I will never make another assumption about a celebrity. I don’t want to be surprised when it comes out that Selena Gomez is secretly into erotic asphyxiation and having hot candle wax dripped all over her soft, naked body. In fact, I’m going to go beat off to that exact scenario right now just to fully prepare myself in case Us Weekly runs a shocking exposé later this week. It would be irresponsible not to.
