Brad Pitt doesn't talk about his struggles with alcoholism often, but he opened up a bit at the National Board of Review Annual Awards Gala on Wednesday night.

The Once Upon A Time... In Hollywood star won Best Supporting Actor at the gala, and was presented the award by another well-known Brad, Bradley Cooper. The 56-year-old actor embraced Cooper on stage and then revealed that his good friend helped him get sober.

"Thank you, Bradley. Bradley just put his daughter to bed and then rushed over to do this,” the actor joked, referring to Cooper's young daughter, Lea. "He's a sweetheart."

"I got sober because of this guy," Pitt continued, in a heartwarming moment. "And every day’s been happier ever since. I love you, and I thank you."

He also joked a little about the National Board of Review during his acceptance speech. "I know very little about the National Board of Review," he said. "You guys have been around for a century? I know so little, other than you love films. I started to Google you, look you up and I thought, 'Fuck it! I love films too. That's good enough for me."

The Ad Astra actor joined Alcoholics Anonymous after divorcing Angelina Jolie in 2017 and has been sober ever since. In an interview with GQ Magazine back in 2017, he said he let alcohol go because he didn't "want to live that way anymore."

"I just ran it to the ground,” the actor recalled. "I had to step away for a minute. And truthfully I could drink a Russian under the table with his own vodka. I was a professional. I was good."
