During an interview with Access Hollywood's Billy Bush on his radio program, The Billy Bush Show, the host asked Lovato if she'd ever dated any of the Jonas Brothers, "Umm, maybe," she said coyly.
"Which one? Joe?" asked Bush, to which Lovato said, "Yeah. He's actually… he's my best friend."
Pressing for clarification, Bush said, "So you guys went from boyfriend-girlfriend to best friends?"
"No kind of the opposite," the 17-year-old Sonny with a Chance star explained.
"Oh? So you're dating him now?" asked Bush.
"Umm, yeah he is my best friend and he is incredible," Lovato finally confessed.
Lovato described her Camp Rock 2 costar as a "complete gentleman," who "treats me to the most amazing places."
She added, "He's perfect."
Lovato first met Jonas, 20, on the set of Camp Rock in 2007 and toured with the Jonas Brothers the following year. The pair have long been rumored to be a couple, which Lovato had previously denied. The pair recently filmed a video for their duet "Make A Wave."
