Nick Jonas does the world a favor, shares surprisingly buff shirtless selfie

nick-jonas-shirtless-selfie-instagram.jpgSometimes it feels like humanity is simply trudging along in a cold, dark world, replacing one day with the next, so thanks be to Nick Jonas for doing his part to brighten everyone's life.

The boy band hunk shocked and delighted fans on Tuesday (July 30) when he took to his Instagram account with a shirtless selfie that showed off a pleasantly surprising ripped physique. (It's worth nothing that he's two months shy of turning 21 -- so feel free to ogle without feeling like a creep.)

"I never do this but ... Healthy living and fitness update. Post workout picture. #diabeticinshape #2.0," Jonas wrote in the caption for the rather impressive photo. (The singer was diagnosed with Type I diabetes when he was 13.)

Jonas' body isn't the only thing he's been hard at work on. He and big brothers Kevin and Joe have been logging some serious hours in the studio for "V," their fifth studio album as The Jonas Brothers, their first since 2009's "Lines, Vines and Trying Times." The album is expected to be released this September.

Did Jonas' surprisingly sexy snapshot work for you or is it too much?
