Rory Culkin has become a dad.
The 36-year-old actor and his girlfriend, cinematographer Kate Arizmendi, welcomed a baby girl named Havoc Moon into the world on May 24, and she announced the news the following day on her Instagram Stories.
Kate posted an adorable shot of their bundle of joy sleeping with the caption: "Her in the womb while I'm screaming System of a Down. We're so in love with you."
In a second story, Kate uploaded a photo of her and Rory's daughter looking wide-eyed down the camera, with the caption: "15 mins after pushing her out and so alert and excited about life already.
"Also hello girl baby Rory."
And in a third story, Kate posted a shot of Rory cradling Havoc whilst sitting in a chair, with the caption: "Best papa."
In January, Kate announced her pregnancy on Instagram, and she edited the caption to include Havoc's full name and date of birth after she was born.
She uploaded multiple shots, including of herself showing off the then-blossoming baby bump, and sonogram pictures.
Kate penned alongside the pictures: "My feed (and brain) has been consumed with such negativity and pain in the world that I thought I’d bring some light by announcing how ridiculously excited we are to be living in Havoc’s world in a few months.
"We love her. She rules us already. Havoc Moon Alva Culkin 05/24/2026."
Fans showered Kate and Rory with congratulatory messages, as one typed: "I'm so unbelievably happy and excited for you guys! Congratulations."
A second supporter wrote: "The wildest best ride there is! Sending you 3 lots of love (sic)."
And a third follower reacted: "This is the best news evah. Love to you two (soon to be three) beauties Kate xxx (sic)."
The Lord of Chaos star Rory and Kate have been dating since 2023.
In 2018, he married cinematographer Sarah Scrivener in New Orleans, Louisiana, with professional wrestling manager Paul Heyman, 60, officiating.
Rory and Sarah - who met on the set of Scre4m in 2010 - split in 2022.
He is the youngest Culkin sibling, including fellow actors Macaulay Culkin, 45, and 43-year-old Kieran Culkin.
