Olivia O'Brien has alleged that she learned Pete Davidson had moved on with "a more famous woman" through Snapchat in 2020.
The former Saturday Night Live cast member faced criticism last week after discussing female content creators during a Variety interview.
Responding to an Instagram post covering those remarks, Olivia accused the comedian of leaving her in 2020 without telling her, saying she discovered his new romance on Snapchat.
"I was dating him in 2020 and found out we were no longer together by seeing on snapchat daily mail that he went public with a more famous woman lmaooo," she wrote. "He is an absolute joke of a human being."
In another comment, Olivia wondered how Pete managed to pursue a different relationship while staying in such frequent contact with her.
"Not sure how he has the time considering we were texting 24 hours a day and falling asleep on facetime when we weren't together," she alleged. "Busy boy! lmfao."
Olivia previously discussed her connection with The King of Staten Island actor on the BFFs podcast in 2022, responding to speculation that he had broken things off with her to date Bridgerton actress Phoebe Dynevor.
"He texted me and was like, 'I'm seeing someone else. So, like, I can't,'" she recalled during that appearance, while also calling him "really funny" and a "really sweet guy".
At the time, the actor’s representatives rejected her account and denied that the pair had dated.
"There is no truth to this," they stated, explaining that Pete and Olivia "were friends and hung (out) a few times".
Olivia later pushed back against the coverage, saying her remarks had been presented without their proper context.
"I never claimed to date anyone. Stop trying to start weird drama over me texting someone 2 years ago. Jesus Christ," she posted on Instagram Stories.
Following his relationship with Phoebe, Pete was romantically linked to Kim Kardashian, Chase Sui Wonders, Madelyn Cline and Elsie Hewitt. He and Elsie had a daughter in December 2025 before separating earlier this year.
