Bryan Bedder/Getty Images Comedian John Mulaney, a Chicago native, reportedly has entered rehab to address his addiction issues with alcohol and cocaine. A report from Page 6, confirmed by other news outlets, said the former “Saturday Night Live” writer and host checked into a Pennsylvania rehab facility over the weekend. The 38-year-old Emmy winner grew up in Lincoln Park and graduated from Saint Clement School and Saint Ignatius College Prep. He has been open in discussing his sobriety issues, once saying he started drinking at the age of 13. “I drank for attention,” he told Esquire in 2019. “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.”
