Nick Jonas Celebrates 22nd Birthday in NYC

 He has a lot on his plate these days, and Nick Jonas combined his 22nd birthday festivities with some promotional duties last night (September 16) in New York City.

The “Who I Am” hunk dropped by the South Street Seaport to blow out the candles on his birthday cake before debuting the music video for his brand new single “Jealous.”

Of his latest ditty, Nick told press, “I think what’s great about this song … is that it opens up the conversation that men are afraid to have. Jealousy happens and it’s OK.”

And just to prove that he’s in control of his own jealousy, Jonas put his knockout girlfriend Olivia Culpo in the clip. As it turns out, she’s quite the cellist!

Happy Brithday Nick!
