Actor Denise Richards insists she would never rekindle her romance with ex-husband Charlie Sheen because she is “too old” for him. “That door is closed. I think he and I are better as friends, mutually taking care of our daughters. I’m way too old for him now. I’m way past his age range,” contactmusic.com quoted the 40-year-old as saying sarcastically for Sheen’s fascination of young girls. Richards, who divorced the Two and Half Men actor in 2006, has two daughters with the actor — Sam, seven, and Lola, six.
