Comedian Steve Harvey fought back Monday after his ex-wife posted a series of YouTube videos accusing him of infidelity during their marriage and being ruthless during their divorce.

In three videos, Mary Harvey accused the best-selling author of being a chronic cheater and also claimed her ex-husband took their son Wynton and left her destitute after their divorce in 2005 after 16 years of marriage.

In 2007, Steve Harvey married Marjorie Bridge, who his ex-wife claimed he dated while his was still married.

“After all this time the reason that I really want to speak out right now is that I really need some closure with this situation,” Mary Harvey said in one of her videos.

“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,” his lawyer said in a statement, according to People magazine.

“We are taking the necessary legal steps to rectify this matter to the full extent of the law,” the statement added.

Harvey, 54, has been married three times. He starred in an eponymous WB sitcom from 1992-2002 and currently hosts a syndicated radio show as well as the family TV game show “Family Feud.”

He has authored two relationship advice books — “Act Like a Lady, Think Like a Man: What Men Really Think About Love, Relationships, Intimacy, and Commitment” that was published in 2009 and the 2010 book “Straight Talk, No Chaser: How to Find, Keep, and Understand a Man.”
