Joe and Nick Jonas lunch with friends in NYC

Joe Jonas and his girlfriend Blanda lunch with Joe's brother Nick and a few of their friends in NYC on Friday.

I was cracking up when Nick just randomly started air drumming in the video. And making everyone pay him back for lunch, including his own brother (I'm guessing, since Blanda gave him money.) Gotta stay on top of those finances, right Nicholas?
