Denise Richards Turns Down 'Men' -- She Has 'Charlie' Issues

Denise Richards has turned down an offer to appear on the premiere episode of "Two and a Half Men," because she thinks Charlie Sheen would make her life miserable.

Sources connected with the production tell TMZ ... producers offered Denise a guest starring role for the debut with Ashton Kutcher, but they say she told them she wouldn't do it because "She would never hear the end of it from Charlie."

No doubt -- Chuck Lorre is trying to stick the knife in as far as he possibly can because ... well, he hates Charlie's guts. But we're told Denise just wouldn't play along.
