At nearly 40 years old, Macaulay Culkin sat down for his first in-depth interview in years.

And it seems like nothing was TMI for the iconic former child actor as he dove into discussing his relationship with Michael Jackson, his sister’s unexpected passing, and his past drug use.

No Topic Off-Limits During Macaulay Culkin Interview

The Home Alone star who appears on the latest cover of Esquire has remained a household name for decades, despite having been gone for so long, turning into “a kind of nether-celebrity,” as the article puts it. Culkin was certainly an open book for the interview.

The magazine’s profile of Mack, which he prefers to be called these days, was accumulated over multiple days’ worth of interviews.

Toward the middle of the published profile, Culkin chats about Michael Jackson and his former relationship with the King of Pop.

He recalls the last time he ever spoke with Jackson before his passing, which was in the restroom of the courthouse where Culkin famously testified in Jackson’s defense in 2005. Jackson happened to enter the restroom during a recess, and said to Culkin, “We better not talk. I don’t want to influence your testimony.”

They had a laugh and hugged, but Culkin says he remembers the pop superstar looking “whipped. Exhausted. Drained.”

Culkin Chats About Relationship With Michael Jackson: “He Never Did Anything to Me”

Culkin sets the record straight on his relationship with MJ, too, saying, “He never did anything to me. I never saw him do anything. And especially at this flash point in time, I’d have no reason to hold anything back. The guy has passed on.”

He also touched on his sister’s passing eleven years ago. She was only a year older than him, and she was hit by a car in Los Angeles and died the next day.

His sister had called to compliment him after watching his film, Party Monster, before heading to a nearby store for “Gatorade and cigarettes,” when she was struck by a car.

“I had that last conversation with her, and she told me to stay focused and enthused,” he says of their last conversation together.

Culkin Opens Up About Drug Use

As for his drug use, he says he never got out of control, but it led him to where he is now.

“I played with some fire, I guess is the best way to put it,” Culkin said. “At the same time, I’ve never been to rehab or anything like that. I’ve never had to clean out that way.”

“There were certain times when I had to catch myself, once or twice. ‘You’re having too good a time, Mack.’ But I never went so far down that road where I needed outside help. I wouldn’t be the person I am today if I hadn’t had drugs in my life at some point or another,” he continued.

“I had some illuminating experiences–but also it’s f*ckin’ stupid, too, you know?” Culkin added. “So besides the occasional muscle relaxer, no, I don’t do drugs recreationally. I still kinda drink like a fish. I drink and I smoke. But I don’t touch the things. I do love them. They’re like old friends. But sometimes you outgrow your friends.”
