“It’s weird living with my mom and sister because, like, I’ll see a strange dude in the house and I don’t know if he’s some dirtbag preying on my sister or the saint who’s going to take my mom off my hands,” he told his costarColin Jostduring aWeekend Updatesegmentin May 2019.
So, who is Pete Davidson’s sister? Here’s everything to know about Casey Davidson and her relationship with the comedian.

InThe King of Staten Island,Maude Apatowportrayed Scott’s sister, a character based on Casey.
“[She’s] a very strong female character,” Apatow said during a2020 interview with PopCulture.“The movie takes place at this breaking point with his sister and his mom, like everyone is just about to break. They’re all very fed up, and I play a frustrated character who you can tell has had the exact same conversation with this person 8,000 times, and they’re just not listening.”
The Davidson family inspired the film, and Apatow tried hard to do her character justice. She simultaneously wanted to stay true to Casey’s essence and add her own spin to the role.
“I didn’t want [Casey] to think I was doing an impression of her,” Apatow noted. “I didn’t really spend that much time with her before the movie started. I tried to get as much information about her and their dynamic, and then I kind of just made it my own. And then afterward, I’ve got to know her really well, and we had dinner the other night — and she’s the best. So, hopefully, I did her proud.”
