Joe Jonas is dating Demi Lovato. While the Jonas Brother hasn’t opened up about his new relationship, the Sonny With a Chance star has confirmed it. Demi told in a radio interview, “Yeah [we’re dating]. He’s my best friend and he’s incredible. He’s a complete gentleman; he takes me to the most amazing places.... He’s perfect!” But Joe remains mum-“He doesn’t really care.They both knew it would come out eventually. I think he would have rather them do it together, but he’s fine that Demi let it slip,” said a source.
