A reputed Mafia figure pleaded guilty Wednesday to charges he conspired to assault the now-husband of former “Real Housewives of New Jersey” star Dina Manzo.

John Perna, 43, of Cedar Grove, admitted planning and carrying out the July 2015 attack during a videoconference in federal court.

Perna and Dina Manzo’s ex-husband Thomas Manzo were charged with the assault earlier this year. Federal prosecutors say Manzo hired Perna to commit the attack in exchange for a lavish wedding reception at a restaurant where Manzo is an owner.
