John Mulaney, 38, an American stand-up comedian, actor, and writer, reportedly has entered a rehabilitation center to address his ongoing addiction issues with cocaine and alcohol, according to a report from Page 6.

The report and other news outlets have confirmed that the former Saturday Night Live (SNL) writer and host “checked into a Pennsylvania rehab facility over the weekend.”

The Emmy winner, who grew up in Lincoln Park, graduated from Saint Clement School and Saint Ignatius College Prep.

He has discussed his struggles with drugs and drinking in his stand-ups. Once, he even said that he started drinking at the age of 13.

Mulaney told Esquire in 2019, “I drank for attention. I was really outgoing, and then at 12, I wasn’t. I didn’t know how to act. And then I was drinking, and I was hilarious again.”

The Chicago-native spent nearly four years writing for SNL, where he helped create Bill Hader’s Stefon character. Mulaney occasionally appeared as himself on Weekend Update.

Mulaney returned as a host years after his departure in 2012, fronting the show four times and winning acclaim for each, according to Chicago Sun-Times.

He was the creator and star of the Fox sitcom Mulaney, a semi-autobiographical series about his life.

Mulaney has also played George St. Geegland in a comedic duo with Nick Kroll, most recently in Oh, Hello: the P’dcast.

Last month, he joined the writing staff of Late Night, starring his friend Seth Meyers. He said at the time, “I like having a boss and having assignments to do. When I’m in charge of something, not so much the best thing.” The article was originally published in Chicago Sun-Times.
