The "Jealous" singer recently played a game of "Guess the Bulge" with Sugarscape, and it's clear the Jonas Brother is just not feeling it.
Check out the video above to see how many "bulges" Nick gets right!
The former Disney star -- who recently did a photo shoot where he showed off his own package -- was a pretty good sport about the game, though.
"I hope I get these wrong," he said before starting, with a laugh.
While the 22-year-old didn't get too many "bulges" right, besides identifying himself and Justin Bieber, he did share a story about a recent sex scene he shot.
"You know, when you're doing sex scenes in a movie you wear that," he explained, while looking at a picture of an actor in nude underwear.
"You wear nude underwear when they're doing a shot with your ass. I just did a TV show [DirecTV's Kingdom] where I had a couple sex scenes and there's like a shot of my ass at one point. And then they have [underwear] that just covers the front with little sticky things."
We'll have to make sure we tune into that episode -- what do you think about Jonas' efforts? Sound off below and check out the gallery to see even more sexy stars!
