The ex-husband of 'Real Housewives of New Jersey' star Danielle Staub is suing her for defamation, saying recent claims that he raped her and murdered their dog during their marriage has scarred him emotionally and damaged his business.

TMZ reports that Kevin Maher, who was married to the Jersey girl for a year in the 1980s, filed a lawsuit Thursday in L.A. County Superior Court. He has received "serious and outrageous threats" since Staub made horrific claims in a PEOPLE article in June.
