Butch Patrick — who played Eddie Munster on the 60s TV show “The Munsters” — checked into a New Jersey rehab center to get help for a 40-year addiction to cocaine, marijuana and alcohol, TMZ reported Thursday.

A rep for the 57-year-old actor told the celebrity news website that Patrick wants to “get a grip on his addiction and educate himself” at the facility in south Jersey.

Patrick’s family have wanted him to seek help for a long time and they are “very happy and supportive” of his decision, the rep added.

In July, Patrick announced he was marrying a long-time fan of the sitcom, former Philadelphia Eagles cheerleader Donna McCall.

McCall said they broke up in early November, though, shortly before her ex entered rehab.
