On Wednesday's episode of MTV's The Real World: Las Vegas, Dustin Zito acknowledged his gay porn past to his girlfriend.

Zito, who appeared as “Spencer” on gay porn sites Fratmen.com and Fratpad.com, had previously made homophobic comments to housemates on the reality show's 25th season.

On the episode, Zito, 24, at first attempts to deny he had sex on camera.

“You got taped having sex,” Heather says. “It's all over the Internet.”

“Wait, what? I didn't get taped having sex. Yeah, OK, I got naked and stuff. There wasn't no touching involved.”

“So, you never did anything where you touched anyone else?” she asks.

“On a video, yes, I did,” Zito replies.

In earlier episodes, Zito appeared to make homophobic comments.

“People were put on the Earth for one fucking reason and it is to reproduce,” he once told his roommates.

Zito made a brief reference to this former gay-for-play past during the show's season premiere.

Several gay porn blogs have alleged that they were asked to remove photos and videos of Zito as Spencer engaged in gay sex.

“After I linked to images of Dustin's anal sex scene on my website, reality blurred, Fratmen's [executive producer John] Marsh sent me an email message suggesting, bizarrely, that the video may never have existed or that 'one of the performers was under 18 years old on the date of production,'” wrote Andy Dehnart at TheDailyBeast.com.

Wednesday's episode drew the show's largest audience in 3 years. More than 2.5 million viewers tuned in for Zito's acknowledgment.
