Nick Jonas has shown that he's not afraid to show a little skin here and there. Jonas has stripped down to his underwear a few times for photoshoots, so how well would he be able to spot other male celebrities' bulges?

Sugarscape recently interviewed the singer and got him to play a game of "Guess the Bulge" featuring photos of five celebrities, including Justin Bieber, Harry Styles, Liam Payne, Ashton Irwin of 5SOS and Zac Efron.

"I hope I get these wrong," Nick admits before he begins guessing the photos.

The video is admittedly a bit awkward to watch, as Nick looks somewhat uncomfortable staring at other guys' crotches but the good sport that he is, Nick plays along and actually successfully guesses a few right with the help of some clues.

We won't spoil for you the results but we wonder: Could you do better than how Nick did in the video?
