Nick Jonas & Shawn Mendes Perform for a Good Cause in NYC!

Nick Jonas sports a little scruff while attending the Musicians On Call 15th Anniversary Celebration held at ESpace on Tuesday evening (November 18) in New York City.

The 22-year-old singer was joined by fellow performers that night, Jessie J and Shawn Mendes, as well as Pete Wentz, Nick Lachey, and Carly Rose Sonenclar.

“I would love to have a band up there, but I would also be fine doing the acoustic thing too,” Shawn recently told JJJ about opening for Taylor Swift. “The acoustic thing is a lot of pressure. I haven’t been playing guitar for that long and Ed [Sheeran] is amazing at that, so it’s hard to kind of follow that.”
