Actress Demi Lovato has confirmed that she and fellow Disney star Joe Jonas are dating.

Lovato, 17, broke the news during a radio interview on 'The Billy Bush Show' on March 12, when she was asked if she had dated a Jonas brother.

"Umm, maybe," the New York Daily News quoted her as replying.

Bush grilled her until she admitted that the brother in question was Joe, 20.

"So, you're dating him now?" Bush asked.

To which Lovato replied, "Yeah, he is my best friend and he is incredible."

Jonas and Lovato met in 2007 on the set of the Disney show 'Camp Rock'.

Rumours of a romance began circulating last October when Lovato and Jonas were seen on a double date in Toronto with another Jonas brother, Kevin, and his then-girlfriend (now wife) Danielle Deleasa. (ANI)
