Actress Debby Ryan has given birth to her first child, welcoming baby Felix Winter Dun with husband Josh Dun, drummer of Twenty One Pilots.

Ryan posted the birth announcement Saturday (Dec. 13) on Instagram, where she shared a personal video clip of herself in a birthing tub, as well as the first public photos of the couple’s child, including a snapshot of Josh Dun holding their newborn.

“We sat under the full moon— the cold supermoon— reminiscing on our life as a family of two, and told the child I was harboring that we were ready to become three. By midday, Felix was born under christmas lights with snow outside our bedroom window, right into her father’s hands,” Ryan captioned her post.

The actress said her husband was “an incredible teammate,” and thanked her birth team and the women who provided support during her pregnancy. Ryan then wrote about baby Felix, whom she affectionately called “lil moonbeam.”

“Her hair is made of silk and her breath smells like vanilla ice cream and every chirp, squeak and whimper is music and everytime I look away and look back, she’s gotten smaller somehow,” wrote Ryan. “I know too soon, I’ll look away and look back and she’ll be bigger and bigger still so for now I’d like to spend my days trapped under the immovable 8 pounds of Felix Winter Dun. I’ve been a lot of things but her home, a grow light, a portal to bring a new soul into the world— these are my greatest honors. Welcome to earth lil moonbeam. Love you forever.”

Dun and Ryan were married in a New Year’s Eve ceremony on Dec. 31, 2019, a year after the two got engaged.

Ryan, who had her breakthrough as a Disney Channel series regular on Jessie (2011-2015) and The Suite Life on Deck (2008-2011), most recently appeared on American Horror Stories and in the film Turtles All the Way Down (both in 2024). She’s next expected to be seen in celebrity thriller Famous alongside Zac Efron, Phoebe Dynevor, Nicholas Braun, and is set to topline sci-fi thriller Orion.

Twenty One Pilots just earned their 13th career No. 1 on the Alternative Airplay chart with their latest single, “City Walls,” marking their third No. 1 on the chart this year following “The Line” (in August) and “The Contract” (in February). The band ties Cage the Elephant and Green Day for the third-most No. 1s on Alternative Airplay since the chart began in September 1988. (Red Hot Chili Peppers hold the record with 15 Alternative Airplay chart toppers.)

Their latest studio album, Breach, debuted at No. 1 on the Billboard 200 in September.
