In 2018, Culkin spoke about his intentions of starting a family with Song during an appearance on The Joe Rogan Experience podcast, saying, at the time, that he wanted to "make some babies."

"This one's a good one, so I'm probably going to put some babies in her in a little bit," he said, laughing. "I mean, we've definitely been practicing."

"I'm going to have some pretty babies. She's Asian, so I'm gonna have tiny little Asian babies. It's going to be adorable — a bunch of Sean Lennons running around the house, that's what I'm looking for," he added, referring to the son of Beatles member John Lennon and Yoko Ono.

Culkin has recently been spotted filming the upcoming American Horror Story season 10 with costars Leslie Grossman, Sarah Paulson, Kathy Bates, Billie Lourd, Evan Peters, Adina Porter, Lily Rabe, Angelica Ross, and Finn Wittrock.
