Jason Aldean and his wife, Brittany Kerr, are expecting their first child together. The couple shared the exciting news on social media on Monday evening (May 8).

"Been hard to keep this a secret, but we couldn't be happier to add to our family," Aldean writes on Instagram, along with a photo of himself and Kerr, and their two dogs, sitting next to an open oven with a bun in it ("bun in the oven" -- get it?). She's wearing a shirt that says "Baby Mama," while he's wearing one that says "Baby Daddy."

This child will be Kerr's first and Aldean's third: The singer has two daughters, 14-year-old Keeley and 9-year-old Kendyl, from his first marriage.

"This journey for us has been full of many happy times and also many tears ... The biggest roller coaster we have ever been on, without a doubt!" Kerr writes on Instagram. "All of the moments of heartache were followed by the biggest blessing in the entire world!!
