Are things OK between Demi Lovato and Joe Jonas?

Has Demi Lovato lost all respect for ex-boyfriend Joe Jonas?

The Disney star, who was dumped by the middle Jonas Brother earlier this year, is apparently furious that Joe has brought his new girlfriend (Ashley Greene) on tour with them.

“You know, I don’t have advice for anybody on that. You gotta brush it off,” she told Hollywoodlife.

“I think there’s a certain level of respect that’s lost when that happens, but you can’t do anything about it other than to just keep going and be glad you have someone in your life that you can think about and spend your time with.”

Demi also spoke about having her heart broken – although she didn’t say who by.

“My big fear is falling for someone that you love more than they love you,” she said.

“Boys are so easy to fall in love with and they break your heart!”

“That’s what happened to me last year, I got my heart broken by a guy.”

“I was in South America working and was devastated for a week — like crying my eyes out. I even cried on stage.”

“I tried getting back together with him even though he really hurt me, but in the end we both knew it was over as it just wasn’t working.”
