Demi Lovato and Joe Jonas Demi Lovato and Joe Jonas

That was fast.

Joe Jonas and Demi Lovato have split after a few months of dating — but contrary to reports, they did not break up over the phone.

"I'd like to clear a few things up. First, Joe and I did split but it wasn't over the phone. Things didn't work out but we'll remain friends," Lovato tweeted. "Secondly, I am NOT dating anybody already. Nothing is more important to me than the relationship I have with my fans. Just thought you guys should know this."

Jonas — who infamously dumped Taylor Swift in 2008 over a "27-second" phone call — added that he initiated the break-up with Lovato, with whom he went public in March."Demi and I knew going into our romantic relationship that it may not be an easy one," Jonas told People. "I realize over the time we have shared together that I feel I care more about our friendship right now. It was my choice to break up but I love her as a friend. She's been there for me when I needed her. I will continue to be her friend and be there for her."
