A reputed mobster who assaulted the then-boyfriend and now husband of former "Real Housewives of New Jersey" cast member Dina Manzo in exchange for a deeply discounted lavish wedding reception has been sentenced to more than two years in federal prison. John Perna, 44, of Cedar Grove, New Jersey, must also pay $17,816 in restitution as part of the 30-month sentence he received Thursday, according to federal prosecutors. Perna had pleaded guilty last December to committing a violent crime in aid of racketeering activity.
