NEW YORK – Denise Richards and ex-husband Charlie Sheen have come so far that it’s almost hard to believe they were once in such a vicious divorce battle that she filed a restraining order against him and claimed he threatened her.

Now, the exes are friends and even co-stars. Richards appears on an upcoming episode of Sheen’s new FX sitcom “Anger Management,” which premieres today. She said it was his idea for her to do the show.

“It’s actually great working with him,” Richards said in a recent interview. “I like working with Charlie. We met working together and we worked together when we were married, and this is the first thing we’ve worked on since our divorce. But I’m very excited for his show and I think it’s very funny, and I was, you know, honored that they wanted me to be a part of it.”

Sheen and Richards even recently told Rolling Stone magazine that they’re “like best friends now” and he tells her everything. He even said in the magazine that he’d still like to have sex with her.

“I would rather him say that than say some other things,” Richards said, laughing.

They might be buddies now, but Richards is cautious to add that things aren’t always smooth sailing between the two. “We’ve been in, I would say, a good place for quite some time. … You know it’s up and down, too. I take it day by day.”

The two divorced in 2006. They have two young daughters together, Sam and Lola.

Besides “Anger Management”, Richards also has a role in the new Tyler Perry movie called “Madea’s Witness Protection” which opens Friday.

Ensler’s latest opens this fall off-Broadway

NEW YORK – A play based on Eve Ensler’s 2010 best-seller “Emotional Creature” is heading off-Broadway.

Producers announced Wednesday that the stage adaptation, also written by “The Vagina Monologues” author, will be performed at The Pershing Square Signature Center this fall.

The play, starring six women, is a collage of monologues and chat sessions about body image, dieting, sex and abortion, among other topics. There is also peppy music by Charl-Johan Lingenfelder.

Previews begin Oct. 26 with an opening night set for Nov. 12.

“Emotional Creature” was workshopped at New York Stage and Film at Vassar College in August 2010, with subsequent stagings in Johannesburg and Paris. It had its world premiere this month at Berkeley Repertory in California.
