Denise Richards' camp say she was completely surprised a judge ruled ex Charlie Sheen can stop paying her child support.Richards, 50, was not present for the hearing, in which an LA judge adjusted Sheen's child support payments to 'zero dollars a month' in light of the fact daughter Sami, 17 is now living with her father.Sources close to the star claim that she was'blindsided'by the decision, and also accused Charlie - who she also shares daughter Lola, 16, with - of 'manipulating the situation.'She also says that Lola is still living with her, therefore Sheen still needs to pay.
