Rory Culkin Steps Into Fatherhood With Daughter Havoc Moon

The Culkin family keeps growing. Rory Culkin, the quieter sibling in Hollywood’s most famous acting dynasty, has officially become a dad. His girlfriend Kate Arizmendi announced the arrival of their daughter on Instagram over the weekend, introducing the world to Havoc Moon—a name that’s about as bold as the Culkin family legacy itself.

The couple, who’ve been together since 2023, welcomed their newborn daughter on Saturday. Arizmendi, a well-known cinematographer, shared a tender shot of the sleeping infant with her hands curled beneath her chin, paired with a caption expressing the depth of their love for their new addition. It’s the kind of announcement that feels both intimate and intentional—classic modern parenthood meets celebrity reveal.

What makes this moment particularly interesting is how it extends the Culkin family tree into yet another generation. While Rory’s becoming a first-time dad, his older brothers are already deep in the parenting game. Macaulay Culkin has two kids, and Kieran Culkin has three—so Havoc Moon is entering a household already primed for uncle duties and family-centric storytelling. Rory’s had plenty of practice with those nieces and nephews, which probably counts for something when you’re sleep-deprived at 3 a.m.

This is Rory’s first child with Arizmendi, though he was previously married to Sarah Scrivener, whom he met on the set of Scream 4 back in the day. The pair divorced without any kids together, so this moment genuinely marks Rory’s entrance into parenthood proper. Kate announced her pregnancy earlier this year, and their family threw them a baby shower just this month, so Havoc Moon’s arrival caps off a season of genuine celebration.

In a way, it’s fitting that the least publicly scrutinized Culkin sibling is becoming a parent right now. Rory’s managed to build a respectable acting career without the tabloid intensity that followed his brothers. Maybe that quieter approach to celebrity is exactly what you need when you’re bringing a kid into a family name that’s been in the spotlight for decades.
