'Dancing with the Stars' 2020: AJ McLean opens up about his addiction recovery from drugs and alcohol

It was an emotionally raw night on "Dancing With the Stars" on Monday when AJ McLean opened up about his decades-long battle with addiction.

The Backstreet Boys singer didn't mince words about the severity of his addiction to drugs and alcohol, which he says started when he was 22 years old.

Speaking with Cheryl Burke, his dance partner who is two years sober, McLean confessed that after he turned to drugs and alcohol, his addiction quickly spiraled out of control.

"I was always a very insecure person. So I felt that I didn't deserve anyone's love. I didn't deserve anyone's affection. Any time I felt uncomfortable, I numbed it," the 42-year-old confessed. "Alcohol and drugs was basically a Band-Aid ... all the while not realizing it was slowly killing me."

McLean says that after shooting the music video for the Backstreet Boys' 2001 song "The Call," where he tried cocaine for the first time, "I don't remember the next two years after that."

"I overdosed twice, and I've literally been in and out of recovery and sobriety up until almost 11 months ago," he continued.

When Burke asked him what made him take sobriety so seriously this time around, the singer got emotional admitting his daughter inspired him. After a relapse in Las Vegas, she refused to cuddle with him and said, "You don't smell like my daddy."

"That was my breaking point," McLean affirmed. "My kids saved my life."

He and Burke both dedicated their dances to their second chance at life, performing a powerful rumba to Kaleo's "Way Down We Go."

"I want to dedicate this to all the addicts out there, struggling, because it's hard," McLean tearfully added when asked by host Tyra Banks about advice he'd have for those working on recovery. "With a little courage, you can overcome!"
