AceShowbiz - Demi Lovato has confirmed longstanding rumors she's dating Joe Jonas, calling the Jonas Brothers' star "perfect" and "incredible". The Disney sensations grew close after appearing together in movie-musical "Camp Rock" in 2008. They sparked rumors of a romance in October 2009 when they were spotted on a double date at a Toronto, Canada restaurant with Joe's older brother Kevin Jonas and his now-wife Danielle Deleasa.

Lovato dismissed reports of a relationship back in November 2009, insisting they "don't have feelings for each other in that way". But she has now come clean about her romance with Jonas - admitting they are a couple and gushing about their relationship in a new U.S. interview.

When asked by "Access Hollywood" 's Billy Bush if she is dating the star, she replied, "Yeah. He's actually .... he's my best friend." Bush probed, "So you guys went from boyfriend-girlfriend to best friends?", to which the teenager said, "No kind of the opposite." She added, "Yeah (we are dating), he is my best friend and he is incredible. He's perfect." Lovato also described her pop star lover as a "complete gentleman," who "treats me to the most amazing places".
