Nick Jonas vs. Joe Jonas: Shirtless Showdown!

Kevin Jonas may be preparing to become a father, but brothers Nick and Joe are engaged in something far more important:

A shirtless-of!

A few days after the Nick Jonas Shirtless Photo That Changed Everything, Joe Jonas has gone ahead and showed off his fine physique... along with a puppy.

The singer didn't include a caption with his photo (bottom, right), so allow us to make one for him: I am Joe Jonas and I am not wearing a shirt. Compare me with my sibling now and decide: Which brother would you rather bone?
