Demi Lovato reportedly has moved on from past lover Joe Jonas. An insider close to Demi claimed the 18-year-old songstress has a crush on Kim Kardashian's brother, Rob Kardashian. The insider even mentioned that it wasn't only Rob who makes Demi interested in but also We the Kings's frontman Travis Clark.

"She likes both Robert and Travis," the insider told Zack Taylor. Still, according to the insider, Demi will not pick one of them as she is still living up the single life. The insider stated, "But (Demi) is really enjoying being single. She has a lot on her plate in the coming months, and just wants to have a good time with it all."

Demi called off her relationship with Joe back in May, after only 2 months from coming clean about their romance. Demi recently stated that she lost respect for Joe after the Jonas Brothers star took his rumored lover Ashley Greene on tour.

"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 told Hollywood Life.
