Charlie vs Denise War over missing $650K

The Sheen has worn off their once amicable relationship...

Denise Richards and Charlie Sheen are gearing up for what could be the ugliest court battle in Hollywood history after the actress alleged in court documents that her ex-hubby owes more than half a million dollars in child support for their daughters Sam, 15, and Lola, 14.

However, an outraged Charlie, 54, insists, “D and her legal posse traffic only in fiction – my day in court is painfully overdue. She is behaving like a coward and the truth will prevail.”

After Denise left Charlie – who was once the highest-paid man on TV – in 2005 while pregnant with Lola, he had to pay her $80,000 a month in support of their girls.
