The 30-year-old star announced the news of their first child's gender in an adorable video on Instagram.
In the clip, Jason and Ashley were standing in front of friends with a giant black balloon.
"Okay, raise of hands, who thought it was a girl?" Ashley asked before the reveal, with a few people in the crowd raising their hands.
Jason then thanked his friends and family who showed up to his party.
The couple tied the knot in 2013.
