After a very bitter breakup, Charlie Sheen and Denise Richards have decided to call a truce to their endless feud for the sake of their children. Charlie's spokesman confirmed: "When it comes to the welfare of their children, any past drama is history." The couple put on a front this week, when they took their girls to a festival and Denise attempted to show her friendly attitude by inviting Charlie's new girlfriend, actress Brooke Mueller, along.

A source told People magazine: "They are working really hard to be good friends and great parents" "Denise wants Brooke to feel comfortable. She put together a bag with toys for her and the girls, along with a card telling her she's glad Brooke makes their father so happy."
