Austin Aaron has a new reason to celebrate Virgo season.
After all, the 13 Reasons Why alum—who played football player Luke Holliday in the Netflix series—announced that he and his wife Kristen Aaron welcomed their first baby, a son named Cal Parker Aaron.
“Welcoming our sweet rainbow baby to the world,” the couple wrote on their joint Aug. 28 Instagram post, which included several photos of their labor journey. “Born August 26th at 1:34pm 7lbs 6oz. So beyond blown away by Kristen, who labored for 42 hours and ended up having a c-section. It was a war but we are so beyond blessed our beautiful baby boy is finally here happy and healthy!”
Indeed, the duo—who got married in November 2021—are already bonding with their little one. They first shared a photo of Cal wrapped in a blanket, before he took his first nap with his dad. Austin, 28, and Kristen also took turns holding him, and their family soon celebrated Cal’s arrival in a sweet video.
Similar to their loved ones, several of the couple’s friends sent them well-wishes in the comments section. The actor’s 13 Reasons Why costar Amy Hargreaves wrote “Oh my goodness, welcome sweet baby!” with a heart emoji, while Tyler Barnhardt—who also starred in the Netflix drama—noted he was “incredibly happy” for them
“Can’t wait to meet you baby Cal,” he continued. “Your parents are a hoot.”
Austin and Kristen first announced they were expecting in March, when they posted several photos of them holding an ultrasound on the beach. His wife then revealed the sex of their baby shortly after, and they told their family the exciting news at a dinner party.
“Baby Aaron is a…. BOY,” she captioned the post with a blue heart and bear emoji. “We can’t wait to meet our little bear.”
