Report: Joe Jonas and Demi Lovato Split!

Rumors are swirling that after dating for about three months, Joe Jonas and Demi Lovato have called it quits.
This comes on the heels of Joe and Demi spending last week together in NYC promoting their movie Camp Rock 2. Sources tell J-14 that there was tension in the air all week and there were even points when Joe and Demi wouldn't sit or stand next to each other and got super awkward when people would ask them about their relationship.
Joe is back in L.A. and Demi is currently touring in South America. Never one to hold back her emotions, Demi tweeted last night, "After the week I've had, I can PROMISE you I will KILL this show tonight... Get ready for one intense concert." She also tweeted, "I can't be changed, I can't be tamed.." referring to her BFF Miley Cyrus' song "Can't Be Tamed."
