Denise RichardsThe ongoing custody battle between Charlie Sheen and Denise Richards has intensified again as Denise asked a judge to protect their children from her ex-husband yesterday.

Charlie was granted limited, supervised visitation of daughter Lola and Sam when the couple split early last year but has challenged the “spying” nature of the visits recently.

In new court papers obtained by Access Hollywood, Denise accuses Charlie of “inappropriate behaviour … and conduct”, particularly related to “his attraction to underage women and his sexual explicitness on the Internet, including revealing his private parts.”. She then asked for “the assistance of the court to obtain orders to protect her children”.

Her lawyer Neal Raymond Hersh added: “She believes that Charlie has significant personal issues which he has failed to address and which require her to take action to protect her children.”

“This is not a vindictive action. Any responsible parent in Denise’s shoes would go to the ends of the Earth to protect her children.”

In response, Charlie released a statement, saying: “Clearly the mother of my children has no interest in responsible co-parenting when it comes to my relationship with our girls.”

“[She] behaves as though she owns our children. She does not. A day of legal reckoning for her is fast approaching.”

“The truth will prevail. It always does.”
