Darren Criss Reveals That Time He Unknowningly Made Out With A Gay Porn Star (Video)

When Criss was starring in the rambunctious "Hedwig &​ The Angry Inch" shows, the actor would pick audience members to kiss during the show.

Just your average late-night interview, amirite?

"I would molest ticket-paying audiences," Criss joked on Tuesday's episode of "Conan."

"I would try and target the most conservative-looking straight boys because that's just more fun. So one night, I remember going for this one dude...and I can't believe I'm telling this story," Criss said. "

So after the show, this guy, who I basically roughed up quite a bit, he has makeup on him and everything... And afterwards, he came backstage with somebody who knew somebody from the show, and he was a good sport about it. And he seemed very genteel and sort of, 'Gee, that was crazy.' And on the way out, [I was] pleased with myself for giving a rollicking good time to a conservative young man."

To Criss' surprise, the "conservative young man" whose face he "molested" ended up being a gay adult film star.

Unfortunately, Criss never found out the name of the guy, but he did dish about his upcoming "bad guy" gig.

“The Music Meister is a trickster that induces people into these alternate realities where there's musical theater numbers happening, as you do when you're trying to legitimize musical theater in the TV space,” the former "Glee" star said. “Also originated by Neil Patrick Harris."

“I'm a nerd. This is really making me look cool," he laughed.

Set in '40s Hollywood, the musical will feature a series of battles and obstacles that "The Flash's" Barry Allen and Kara Danvers must overcome and escape. If someone dies in the musical world, he or she also dies in the real world.

Criss also said his character has a “weird agenda” to teach people the power of song and dance “because it's a musical – that's what you do.”

Conan said he'd be sure to watch since both his kids are fans of the shows.

“I'm certainly hilarious in it,” Criss said. “I'm terrified, actually. I'm curious to see how it turns out.”

What's even better than Criss gushing about his role in the upcoming CW crossover and unknowingly making out with a gay porn star is just how enthused he was to speak to O'Brien.

“It's no secret that I love (dare I say idolize?) #CONAN,” the “Starship” actor tweeted Monday before his interview. “Watch me desperately try to play it cool and fail. Love me some @TeamCoco!”
