A rep for Disney starlet Demi Lovato—who's currently undergoing rehab treatment for "personal issues—stepped forward on Friday to blast rumors that the Sonny With a Chance star had filmed a sex tape, Gossip Cop reports.


The denial came on the heels of a report published on Friday by X17Online, which claimed that Lovato, 18, was "no stranger to filming her sexual exploits" and that a sex tape featuring Lovato with a male partner "will surface soon."


The story goes on to cite a source who claims that Lovato's uncle, Francisco Lovato, served as chaperone for his niece during an August concert and forbid anybody from entering her bus, presumably so she could entertain a sexual partner. A member of Lovato's crew also claims that she would "always kick people off the bus so she could bring random dudes on board and get nasty with them."


Responding to the story, Lovato's rep lashed out,


“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 [X17Online] report is so spotty that it is hard to fully respond. For instance, 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.”


Earlier this week, candid pictures purporting to depict Lovato striking provocative poses leaked onto the Internet, which may have sparked this latest rumor.


Lovato entered rehab in November, following reports that she had engaged in a physical altercation with a backup dancer on her tour.
