Demi Lovato's rep has rubbished rumours she's made a sex tape.
The Camp Rock star, 18, pulled out of her joint tour with the Jonas Brothers last month to enter a clinic.
Since then, wild and unsubstantiated claims have been made about Demi's private life, including that she's made a saucy home movie.
'Perpetrating these completely unfounded rumours from supposed sources while Demi is in treatment dealing with serious physical and emotional issues is disgusting,' the teenager's rep tells TMZ.
'The sourcing on this report is so spotty that it is hard to fully respond.
'We would ask serious news outlets to strongly consider the source of this story before they regurgitate it.'
Demi split from Joe Jonas, 21, in May.
