from www.popeater.com - Note to anyone wanting to hang out with actor Charlie Sheen: Telling him that you are starring in a movie with his ex-wife Denise Richards is not a great ice breaker.

Especially if you are porn star Ron Jeremy.

Jeremy was pretty excited (if you will) about landing a role with Richards in the mainstream film, 'Finding Bliss' and was eager to tell his buddy Sheen when they ran into each other on the red carpet at the Emmys in 2007.

"(Sheen) gave me this big hug on the red carpet," Jeremy tells PopEater, noting that then-girlfriend Brooke Mueller pulled her beau away quickly "like he shouldn't be seen hugging me."

But Jeremy knew that Sheen and Richards had been fans of his memorable stint on 'The Surreal Life' in 2005 when they were a couple -- they had even called to tell him how much he enjoyed the program. Those were distant, happy days.

While friends warned Jeremy not to mention Richards, the famed porn actor couldn't help himself. He took advantage of running into Sheen in the men's room during the awards program to start the conversation again.

"I got him alone in the bathroom, we were both using the sinks," says Jeremy. He happily told Sheen that he was working with Richards, neglecting to inform him of the nature of the film.

"I thought he would get a kick out of it, but he didn't," says Jeremy. "He just gave me this completely blank stare."

Now that's awkward.

At least his experience with Richards was more positive on the film. "She was sweet," says Jeremy.
