Nick Jonas Posts Shirtless Pic On Instagram!

The 20-year-old singer is seen shirtless in the snap, which he captioned: "I never do this but... Healthy living and fitness update. Post workout picture. #diabeticinshape #2.0."

 

 

 

Nick was diagnosed with Type 1 Diabetes back in 2005 and has become a spokesperson for the condition.

 

He told Diabetes Health in 2007: “I have a platform to be able to share my story.  I have this passion to be able to share with young people my age and be a positive light in a situation that might not be so positive.”

 

Nick and his brothers Joe and Kevin are about to release their fifth Jonas Brothers album V, following a three and a half year hiatus.
