Nick Jonas Posts Shirtless Instagram Pic

By  | 

Well, it's officially official. Nick Jonas is all grown up. The 20-year-old singer posted a shirtless pic to Instagram on Tuesday, but wanted to followers to know this won't necessarily become a regular occurrence.

Posting the photo with the caption: "I never do this but… Healthy living and fitness update. Post workout picture. #diabeticinshape #2.0," Nick really has never looked better! We're glad that he's managed to keep up with a healthy lifestyle, even while staying busy on the road during the Jonas Brothers' latest tour.

As you might know, Nick was diagnosed with Type I diabetes at the age of 13, and ever since has been active in his support for the diabetic community. He even created a charity titled Change for the Children Foundation, also partnering with five different charities, with a goal of raising money (and awareness) for diabetes.

Good for Nick! Keep up the good work! What do you think of his shirtless pic? Sound off in the comments!
