Pete Davidson opened up about his sobriety during his latest comedy show at The Fontainebleau in Las Vegas.

The 32-year-old former Saturday Night Live regular shared an anecdote, revealing how his mom, Amy Waters Davidson, inspired him to stop using drugs and alcohol for good.

'I went to rehab this time. I was like, I’m gonna actually do it so I could save some of this money I’m making and stop blowing it on rehab,' he said.

While performing on stage on Saturday, he added, 'I did family week, when, with your therapist, you Zoom your family and they tell you how difficult it is for them to watch you do drugs.' 

Davidson recalled the 'brutal' video call to his mom, during which he had an epiphany about his risky lifestyle.

'She went, "Enough." She f***ed me up. She was, like, "Peter, it’s very hard to be your mom because I wake up every morning with the fear that I’ll turn on the news and see that my son has died. 

'She told me all this on Zoom – from the house that I bought her on drugs. I was like, "Someone’s getting used to things." That got me sober,' he quipped.

He reiterated, 'I remember my mom popped on the screen, and she was like, "Peter, it’s really hard to be your mom. It’s not a fun job."'

He joked, 'I was still, like, newly sober, [thinking], "Well, you’re not f**king that special. What do you do?"'

The actor was raised by a single mom, after his dad, New York City firefighter Scott Davidson, died in the September 11th terrorist attacks.

Davidson welcomed his first child, daughter Scottie, with girlfriend Elsie Hewitt last December.

Elsewhere in his standup set, he discussed fatherhood.

He got candid about not being able to enjoy porn after becoming a parent to a baby girl. 

'[I] got a little girl. It's weird having a little girl,' he said on stage, according to Us Weekly.

He admitted it's 'hard to watch porn...in front of her,' but cracked, 'I still did. I power through.'

Jokes aside, he described being a new dad as 'a lot of fun,' adding that it's been 'great.' 

While on This Past Weekend podcast last September, the entertainer said, 'Thank God that I’m sober.

'I wish I had more time of sobriety ‘cause it’s only been like a year and change, but I’m very grateful that it happened now and with Elsie.'

Months before his daughter was born, he explained, 'In other relationships or when I was, you know – I was a drug addict and very mentally deranged, but that was my goal: "I need to have a kid. I need to get married." Because that's how I grew up.'

In retrospect, the comedian said he was 'not ready' to have a family when he was still in the thick of substance abuse.

'I stopped dating and I was, like, "I need to f***ing get better and I need to be in a place where I could even have a healthy relationship,"' he remembered.

The star told host Theo Von, 'I wasn’t looking for a relationship or looking to have a baby. It all just kind of happened at once, and it’s been awesome.'
