Nick Jonas' Buff Body
Who knew? Jonas Brothers singer Nick Jonas -- the youngest of the three members, behind Kevin Jonas and Joe Jonas -- showed off his surprisingly buff bod in a photo on Instagram on July 30. "I never do this but...Healthy living and fitness update," he captioned the shot. "Post workout picture. #diabeticinshape #2.0"
