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 Thursday. She says it was his idea for her to do the show.
