Nick Jonas made the Internet stand up and saw "wha-aaaa?" when he posted a stunning shirtless selfie on Instagram. But older brother Joe Jonas wasn't about to let his sinewy sibling get the last word: Sporting a shaved head and 'porn stache, JoBro posted a shirtless photo of himself clutching a terribly cute pooch.

Wait a minute! Shaved head, porn 'stache? Is Joe dating Cheyenne Jackson?

Below, another recent shirtless Nick pic, with Wilber Valderama (?) and a lady friend.
