Nick Jonas girlfriend Olivia Culpo makes an appearance in the music video of his newest single, "Jealousy." The single's video will debut today, September 16, which is also the crooner's 22^nd birthday.

Jonas admits that the song was inspired by real emotions.

"I saw someone looking at her ass when we were out one night. It really upset me. The next day I went into the studio and wrote the song. So I got something good out of the experience even though in the moment it was frustrating," he told E! News

The young Jonas, however, admits that it can be flattering that people notice his Miss Universe titlist girlfriend: "Yeah, to a certain degree. It's just when it's constant when you're trying to enjoy the evening that it can be a little bit too much."

In the music video's promo, Nick Jonas girlfriend Olivia Culpo is portrayed playing a cello while clad in black lingerie. The former Disney star gushed about his lady love's appearance: "She's a lot of fun, she's a cellist and she played cello in the clouds in this video, which is pretty incredible scenery."

When asked by E! News if Nick Jonas and Olivia Culpo will soon settle down, the "Chains" singer said, "We're just having fun right now. We have plenty of time for that."
