Penn Badgley and wife Domino Kirke are grateful for their family of six. The couple, who wed in 2017, announced in February 2020 that they were expecting their first child together after previous miscarriages. Their son was born the following September. While Badgley quickly adapted to new fatherhood after the baby's birth, he previously got a taste of parenting while bonding with Kirke's eldest son, Cassius, from a previous relationship. "He's a really good stepdad," the "Half Blood" songstress exclusively told Us Weekly in October 2019 of Badgley. "He doesn't have to be 'dad' so he can have more fun with him. It's really nice. The stepparent thing is definitely uncharted territory for me 'cause I didn't grow up with one, but ... he takes care of him really well." Kirke and Badgley later welcomed twin sons in 2025.
