Swoon? Joe Jonas is bugging out -- but in a good way. The singer shared a shirtless photo alongside his bug-eyed pup via Instagram on Aug. 5. Imitating his furry friend, the Jonas Brother got up close and personal with the camera.

The funny photo comes just days after his younger brother Nick revealed his abs via Instagram on July 30. "I never do this but...Healthy living and fitness update. Post workout picture. #diabeticinshape #2.0," Nick wrote at the time.

And their toned bodies aren't all the siblings are exposing. The two also recently revealed how they feel about becoming future uncles.

"[We're] very excited," Joe, 23, told Us Weekly at Z100's Clear Channel radio studios in New York City about older brother Kevin and wife Danielle Jonas expecting their first child. "I think this is a good time for adding a new member of the family. And you obviously don't really know what to expect until he or she is actually here but then it will all kind of sink in. You just talk about it, but when we're actually able to hold that baby, our niece or nephew, that will be exciting."

Nick, 20, is especially excited for the new addition. The "First Time" singer hopes his future niece or nephew will sport a specific fan-given gift -- a bib that says "My Uncle is hot! And single!"
