Multiple outlets have reported that the pair have split after nine months together.
"Pete Davidson and Chase Sui Wonders have broken up, and both of them are focusing on themselves," one source toldEntertainment Tonight.
Another source told People magazine that Pete is, indeed, "single again. He's out and about and doing really well."
The news of their breakup comes after Pete checked himself into treatment for his mental health in June.
At the time, an ET source said, "Pete Davidson has been in rehab and is being treated for mental health issues. He can be manic and wasn't sleeping well or taking good care of himself, so he decided to go to get help, take a break, and get back on track. Pete is focusing on himself."
He and Chase had been linked since December 2022 after meeting on the set of their horror film Bodies Bodies Bodies.
