In July 2023, Us Weekly reported that Jack Quaid and Claudia Doumit were "still together and are going strong." A source explained that he resembles his mother in wanting to be a private person despite Quaid's increasing public profile, particularly when it comes to romantic relationships. Because of Quaid's desire for privacy, not much is known about his relationship with Doumit. However, they occasionally share photos and tributes to each other on social media.

In April 2022, Quaid shared a birthday message to Doumit on Instagram. He captioned it: "The happiest of birthdays to the Vickiest of Neumans: The amazing @claudiadoumit!!! #happybirthday." The actor included several photos of them on-set and off-set. The following year, Doumit wished Quaid happy birthday on her own Instagram page, alongside several on- and off-set photos and videos. Her caption read "HBD to the one and only @jack_quaid 🎂."

During the SAG-AFTRA actors' strike, Quaid also posted images on Instagram of Doumit and him striking together. The low-key couple clearly knows the difference between secrecy and privacy in their relationship. They aren't secretive about it but private. This seems to work for them as they've already celebrated more than a year together at the time of writing.
