Farrah Superstar: Backdoor Teen Mom is taking the world by storm one sex toy at a time, and everyone is getting in on Farrah Abraham's erotic action — even her ex-boyfriend, Marcel Kaminstein! Marcel and Farrah dated back in 2011 (they met on JDate), but their relationship lasted only a few months.

These two haven't been in touch since their breakup, but Marcel's been following his sexy-exy's new career path and says Farrah's porn is "completely embarrassing."

"My friends never really liked her. She was extremely rude," Marcel tells Celebuzz. "I was surprised how she chose to create and release the tape, being with a porn star. I would have thought she would take the Paris Hilton route if she really wanted to do one."

So, is Marcel going to watch Farrah's tape? This businessman says he doesn't have any immediate plans to feast his eyes on Farrah, but will probably end up watching the X-rated video at some point.

"I’m sure I’m probably going to watch it when my friends call me and say they’ve seen my ex girlfriend," he says.

Way to be supportive, Marcel! We're sure Farrah is thrilled that her former lover is getting a much-needed reminder of what he's missing...
