Jonas went to BPM, a New York gay club, last night and showed off more than his new new song "Jealous."
A fan captured the great moments from last night.
First, here's a snippet of his song "Jealous."
After taking off his suit jacket, Nick opened his shirt to show off those abs.
It was then that he showed off his "fighting skills" and flexed.
The singer did leave his pants on and his shirt around his shoulders. His body is something he is not ashamed of as he shared a shirtless selfie that went viral just last year.
