Jonas Brothers strip on stage

Washington (ANI): Jonas Brothers recently surprised their New York fans - first by inviting them to an unexpected concert and then stripping to their undershirts.

The concert took place at New York's Irving Plaza at night after an announcement the same afternoon on their website. The band played songs from its old album as well as new, in front of the lucky seven hundred fans.

Kevin, 21, Joe, 19, and Nick, 16 then stripped down their clothes to a cheering crowd. However, they stopped at their undershirts.

Nick, who has dated Miley Cyrus in the past, kept silent during the gig about recently spending time with her again. However he shouted to the crowd, "It's never the end, it's a new chapter. This is how it worked in my life," reports People magazine.
