Brad Pitt has paid tribute to Bradley Cooper for helping to get sober in a touching speech.

The gesture was made at the National Board of Review Annual Awards Gala on Wednesday night. Cooper was presenting the event, and when Pitt won Best Supporting Actor for Once Upon a Time in Hollywood, he used his speech as an opportunity to pay tribute to his friend.

"I got sober because of this guy," the 56-year-old actor said. "And every day's been happier ever since."

Referring to Cooper's two-year-old daughter Lea, the veteran actor said: "Thank you, Bradley. Bradley just put his daughter to bed and then rushed over to do this."

Pitt then gave Cooper a thumbs up, adding: "I love you, and I thank you."

This was an insightful moment from the actor, who has rarely spoken publically about his battle with addiction. He spent a year and a half attending Alcoholics Anonymous after he split from his second wife Angelina Jolie, as per E!

However, Cooper wasn't the only famous face Pitt praised during his speech. "Well, it's nice to be able to leave this thing carrying something other than George Clooney."

"I know very little about the National Board of Review," he continued. "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, 'F*ck it! I love films too. That's good enough for me.'"

Needless to say, the crowd found this admission hilarious and Pitt went on to discuss his love of film.

"No seriously, I really, really love film," he declared. "From an early age, they were my view into a world far grander than my backyard. Fascinating characters that I became obsessed with, like Popeye Doyle and R.P. McMurphy or Sonny Wortzik, Woodward and Berstein, Johnny Boy. I think Johnny Boy's in the house somewhere here. I mean, they meant so much to me. I love film, so thank you so much for this. Thank you very much."

As you can imagine, the video of Pitt praising Cooper garnered a lot of positive attention on social media.

One Twitter user wrote: "Pitt has really settled into his effortless cool and I am here for it."

"Brad Pitt is the absolute star of this awards season!" remarked another.

A third wrote: "Brad Pitt makes me laugh. Who knew their [sic] was a quick wit behind that pretty face?"

This is proof that good friends - even if they are famous - are worth their weight in gold.
