The "SNL" star sat down with Jimmy Fallon on Thursday to discuss his latest living situation.
"So, I live with my mom. We bought a house together, but nobody believes that," Davidson said. "I have like a basement that's mine, but that's like an apartment. So I live underneath her."
But he has major plans for his bachelor pad, saying he's enjoying video games, like "Mortal Kombat 11," to make it more like home.
When the two discussed Davidson's obsession with the video game franchise, especially since they're paying him, the comedian admitted to being "lonely" while describing his crush on one of the female characters.
As The Blast reported, Grande and Davidson broke up in October, just four months after getting engaged.
Don't feel too bad for ol' Pete though ... he's since moved on to hottie, Kate Beckinsale.
