He added, “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 was referring to John Lennon and Yoko Ono's son.)

In the story, Culkin brought up the idea of “practicing” for kids again.

Thanks again @nobuloscabos for the fun time and excellent stay. And thanks for selling that shirt. It really made me feel like I belonged.”
