Pete Davidson was high on ketamine at Aretha Franklin’s funeral

Pete Davidson revealed he was high on ketamine — the drug that was in Matthew Perry’s system at the time of his death — while attending Aretha Franklin’s 2018 funeral.

Davidson, who attended the Queen of Soul’s service with his then-fiancée Ariana Grande, recalled the experience in his new Netflix special “Pete Davidson: Turbo Fonzarelli,” which hit the streamer Tuesday.

“It’s embarrassing when you’re not on ketamine anymore, though… I’m embarrassed,” he started. “I was out and about like that. That’s not cool, you know?

“I was at funerals like that. That’s f–ked up, right?” Davidson, 30, asked. “I was at Aretha Franklin’s funeral like that. Yeah, I have to live with that. You know what I mean?”

He quipped, “She’ll never know, but still, that’s not the point. You know what I mean?”

The Post has contacted reps for Davidson and Grande for comment.

Ketamine is a dissociative anesthetic, meaning it makes patients feel detached from their pain and environment.

It can lead users to feel calm and become immobile, and can also act as a pain reliever, cause amnesia, and provide hallucinogenic effects in certain dosages.

Davidson revealed in September that he took the dissociative drug medically as an anesthetic every day for four years before a stint in rehab over the summer.

“If she was there, she would probably be like, ‘Hey, who are you? And what the f–k are you doing at my funeral?’ ” he admitted. Meanwhile, Grande, also 30, sang Franklin’s “(You Make Me Feel Like) A Natural Woman” at the funeral.

“It’s embarrassing. I’m so high, I thought it would be a good idea to go up to her family and go, ‘Hey, I’m just here to pay my R-E-S-P-E-C-T…S,’ ” he cringed.

Davidson has been open about his drug use, issues with mental health, and rehab visits throughout his career. While he often jokes about his struggles in his stand-up sets, his latest special “delivers on what it means to grow up and turn 30, discussing love, life and living in the woods,” according to its synopsis.

Meanwhile, officials announced Perry’s cause of death as being “acute effects of ketamine,” along with drowning, coronary artery disease and the effects of buprenorphine (an opioid).

The “Friends” star, who was 19 months sober at his time of death, was undergoing “ketamine infusion therapy” for “depression and anxiety” at the end of his life. It is unclear if he was using the drug legally or illegally.
