The three clips totalled over 25 minutes in length and accused the star of several instances of infidelity during their relationship as well as claiming that he "stole" their son from them upon their divorce and left her with no financial security following the split.
However, Steve's attorney Bobbie Edmonds told People that there is no truth in the statements and that he is pursuing "legal action" against Mary for the allegations.
"We are appalled and aware of the videos and other fabricated documents... which contained false, misleading, derogatory, disparaging, malicious, explicit and slanderous information about Mr Harvey, his current wife and others," Edmonds said.
"The ex-wife is fully aware of the court's current orders and permanent injunctions which prohibit either party, their lawyers or representatives from discussing and releasing information on the internet and to the media."
The statement continued: "We are taking the necessary legal steps to rectify this matter to the full extent of the law and we will be seeking contempt and sanctions against her for such reprehensible and callous disregard for the court orders."
