Nick Jonas admits that his new single, "Jealous," has its roots in the real world. He told NewNowNext the song was based on an incident that happened not long ago with his beauty queen girlfriend, Olivia Culpo. "We were out and someone was looking at her too long," he recalls. "It was uncomfortable."

Nick also talked to us about his recent appearances at some New York gay bars—and how he hadn't originally planned on showing off his killer abs: "That was not my choice," he jokes. "That was requested of me after a few alcoholic beverages… [but] it was all in good fun."
