Much has been written about Nick Jonas' bulge, particularly after photos surfaced of him wearing super tight pants. In a Sugarscape video published Thursday, the "Jealous" singer agreed to play "Guess the Bulge." As it turns out, determining which penis belongs to which celebrity isn't one of Jonas' specialties.

The hunky singer-songwriter, who is dating Miss USA 2012 Olivia Culpo, has readily embraced his status as a gay icon. Even so, that doesn't mean Jonas has firsthand knowledge of his peers' packages.

Before the game began, he smiled and said, "I hope I get these wrong."

After being handed the first photo, he said, "That's me. I know that."

The second picture, however, required a double take. "I couldn't tell you who that is," Jonas confessed. He learned that it was a One Direction member with "a lot of pubic hair." Unfortunately, the clues didn't help Jonas figure it out. But, after he was told that it was Liam Payne's bulge, he replied, "Ah, of course."

When he was shown a photo of Zac Efron, he asked, "Is this nude underwear here? You know, when you're doing sex scenes in a movie you wear that. 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," he explained. "So, I'm guessing this is an actor. It's tough. This is hard." After being told that the person in the photo starred in High School Musical, Jonas asked, "Is this Zac?" He then said, "Nailed it!"

The next photo was easy to identify, due to the saggy pants. "This looks ridiculous," he said. "It's [Justin Bieber]. That's the plain giveaway. He's the one person in the world who would look that ridiculous."

The fifth photo showed a person wearing swim trunks. "I guess the only clue on this is that tattoo. That's quite a big bulge as well," the interviewer said. "Ah," Jonas, 22, replied. "A lot of One Direction today."

Jonas tried his hardest to examine the evidence in the sixth and final photo. "Teen Choice Awards?" he asked, looking at the surfboard. Jonas was told that the person was in an Australian boy band, but again, he had no idea who the interviewer was talking about. It was Ashton Irwin from 5 Seconds of Summer.

"Ah, of course," Jonas joked. "How did I not know?"
