Nick Jonas: "Jealous" Is Inspired By Real Experience With Girlfriend Olivia Culpo

With his ultra-enviable falsetto (listen to "Jealous" below), physique (hello!) and girlfriend (Olivia Culpo, aka Miss Universe 2012), it's hard to imagine that Nick Jonas is jealous of anyone other than, well, himself. But the JoBro tells us that his slick new single "Jealous" came from an experience with Culpo.

"We were out somewhere and someone was staring at [Culpo] for a little bit too long," the "Chains" singer recalls. "It was uncomfortably long. I kind of got in my head about it for a moment. That's been the really interesting thing about this song and whole idea of jealousy: It's not the best character trait, but it's a very human thing. I think it happens to everybody at different moments. I'm in a very happy relationship and it was all in my head. That's what I pulled from this experience and the song."
