"We've actually become like brother and sister, we really have. Nothing more than that," she said. "We've become very, very good friends."
Their new-found friendship is a far cry from what once was a tabloid spectacle of name-calling and custody disputes. In her 2006 divorce filing, Richards accused Sheen of drug abuse and threatening to kill her, according to People. As recently as March 2011, Sheen labeled his ex a "traitor and loser whore."
Yet, Richards insists that they are putting on a united front for their children's sake: "The stuff between the couple, if you're divorced, it's no longer about you anymore. You have to be a bigger person and make it about the kids, so that's what we are doing. He is who is he, I can't change him, so I've accepted him for who he is."
Her one stipulation, however, is that Sheen remains sober when he's with the kids: "The kids wouldn't be around if he wasn't."
Sheen and Richards tied the knot in 2002, but marital bliss was short lived. Richards filed for divorce in 2005 while she was six months pregnant with their second child.
