Comedian Pete Davidson has a housemate — his mom.

The 25-year-old revealed on “The Tonight Show” with host Jimmy Fallon Thursday evening he lives in a “man cave” (a.k.a. the basement) in the house Davidson said he and his mother purchased together. The pair paid a whopping $4.5 million for the mansion, which includes a private master wing and high-end kitchen, Page Six reported, citing real estate records.

“So I was calling it the ‘man cave,’ but the Mulaneys [comedian John Mulaney and his wife Annamarie] told me that if I call it that, they will no longer be my friend,” Davidson, who currently has a comedy tour with Mulaney, said.

“So now I call it ‘the’ Basement, like ‘the’ Ohio State University.”

“It’s the ‘the’ that’s important,” he clarified as the audience laughed.

The "Saturday Night Live" star added he plans to install an arcade in his area of the home and noted he has recently played the video game “Mortal Kombat 11.”

“Well, they are paying me to be here to talk about it,” he said candidly before joking, “I’m trying to get a helicopter to Coachella.”

Davidson, who sported a “Mortal Kombat” T-shirt and shoes during his appearance on the late-night show, went on to talk about some of the game’s characters — particularly, Johnny Cage.

“There’s this guy that I really like to kill in it because he looks like a real doucheb–,” Davidson said. “This guy Johnny Cage, so he does splits and punches you in the d—, it’s his special move. And he just looks like everybody I grew up with in Staten Island, so I just kill that dude.”

“Also he has like a hot daughter, which is like weird because I’m lonely and she’s like not real. So there’s that in the video game as well, sexual confusion,” he said with a laugh.

Davidson, who recently reactivated his Instagram account following a nearly 5-month hiatus, is now dating actress Kate Beckinsale, 45.
