As the star of Broadway’s “ Hedwig and the Angry Inch,” Darren Criss was required to smooch, straddle and generally “molest” a different audience member each night ― all while wearing fishnets, heels and a sky-high blonde wig.

For the most part, the 30-year-old “Glee” veteran took the simulated hanky-panky in stride, and says he often sought out conservative-looking men to accost for comedic effect. But in a “Conan” interview that aired Tuesday, Criss recalled a performance in which the object of his affection turned out to be, um, slightly less conservative than he appeared.

“I would tend to pick the people who I assumed didn’t know what was going on for the comedy — for myself and for everybody else watching the show,” Criss said. On one particular night, Criss said, he “basically roughed up” a very clean-cut-looking audience member, leaving a trail of “lipstick and glitter” all over the man’s face and body.

Afterwards, Criss said he was introduced to the man backstage, who “was a good sport about it and seemed very gentile and ho-hum.” After the man left, however, a couple told Criss, “That’s our favorite gay porn star!”

“He’s clearly seen much more than I ever have,” Criss, who did not reveal the identity of the actor, quipped. “Apparently, he’s very well-liked, and if I was going to do that, I only went for the best.”

The actor-singer, who recently wrapped a second run as Hedwig in Los Angeles and San Francisco, is back in the Hollywood spotlight. He and his brother, Chuck, have teamed up to form a new, alt-pop duo called Computer Games. The pair released their first EP, “Lost Boys Life,” last week. He’s also signed on for the third season of “American Crime Story,” and will appear on a musical crossover episode of “The Flash” and “Supergirl.”

Of course, that “Hedwig” anecdote begs the question: which gay porn star could it have been?!?!?!
