Inside Pete Davidson's Relationship With His Sister Casey

These days, everyone has heard of Pete Davidson, but it wasn't always that way. After a few minor appearances in MTV shows, the famous comedian caught his big break when he joined the cast of "Saturday Night Live" in 2014 (via Inquisitr). Being just 20 years old at the time, Davidson became one of the youngest cast members to ever join the iconic sketch comedy series. Today, the "Suicide Squad" actor is as famous as he has ever been. Davidson continues to blow people away with his iconic sketches and characters on "SNL," and he makes headlines for high-profile relationships with famous figures such as Ariana Grande and Kim Kardashian.

Unlike some celebrities, Davidson hasn't shied away from revealing details about his personal life (via Screen Rant). Whether it's in an interview or on social media, the Staten Island native has opened up about his drug use and mental health issues on more than one occasion. That being said, there are some things the "Big Time Adolescence" star does not discuss as much, including his family. For instance, did you know that Davidson has a younger sister named Casey? Keep reading to learn more about their close-knit bond.

While he may spend a lot of time in the spotlight with A-list celebrities, when it comes to his life behind the scenes, Pete Davidson shares a quiet, close relationship with his family. In fact, as many of his fans already know, Davidson's longtime roomie was none other than his mother, Amy (via NY Post). The third member of their close family unit is Casey Davidson, the talented comedian's younger sister. Born in 1997, Casey graduated from Marist College in Poughkeepsie in 2019, where she played college basketball (via Distractify).

Despite the fact that the two siblings have a four-year age difference, they couldn't be closer. Casey's Instagram account shows photos of the siblings constantly supporting each other, whether it's Davidson attending his sister's graduation, or Casey watching her brother's comedy performances. The two siblings, along with Davidson's ex, Ariana Grande, even share a tattoo (via Heavy). The Davidson's got the tattoo in honor of their late father, a firefighter who tragically died on 9/11. The tattoo is their father's former badge number, 8418.

Not only is Casey close with her brother, but she has also recently been seen connecting with her brother's girlfriend — at least through social media. When Casey posted a photo of her and her brother sitting court side at a Brooklyn Nets' game, Kim Kardashian responded by liking the post (via E! News).
