“2017, Aaron reached out to me, asked me for help. I said, ‘Look, if you get on a plane, come out to L.A., I will make sure you get into treatment.’ And he showed up,” McLean, 45, says in the clip. “I was shocked, but I was happy, and he checked into a treatment center in Malibu.”

He continued, “A couple days later, I talked to him, and then he kind of went off the map. I think it was maybe two weeks, so I called my friends at the treatment center, and they said he checked himself out.”
McLean also talked about his own struggles with addiction.

“I was a functioning addict. I had been in and out of the rooms since 2001, so for 22 years I’ve been battling my own s—,” he said. “I almost lost my marriage, I almost lost my band, I almost lost my life. The last time I relapsed, which would be 18 months ago, my youngest daughter was kind of the nail in the coffin for me.”
McLean added, “Shesaid I didn’t smell like her dad. That was enough. That pretty much did it for me and I have stayed sober since and I plan on staying sober. It’s a daily thing.”
