Congratulations to Shay Mooney and his fiancee, Hannah Billingsley: The couple is expecting their first child!

Mooney and Billingsley announced the news on Instagram on Saturday (Oct. 8). Mooney shared a photo of himself and Billingsley cuddling and holding a onesie that reads "I'm with the band."

"Gonna have a new band member in the Mooney family ... 2017 is gonna be the start of our best adventure yet!" the Dan + Shay singer writes in the photo's caption, along with a number of happy-face emojis. "Mini Mooney is comin' in hot."

Mooney and Billingsley, who was crowned Miss Arkansas USA in 2013, got engaged on Aug. 9. They announced their engagement on social media a few days later.

Mooney and his duo partner Dan Smyers released their sophomore project, Obsessed, in early June; their current single is "How Not To." Dan + Shay will be out on the road this fall, for their Obsessed Tour. The trek will include shows in both the U.S. and Canada.

“We have been so humbled by the response to our new album and can’t wait to perform live for our fans this fall,” says Smyers. “Our fans inspired the title of the Obsessed album, so it was only fitting to name the tour after the album.”
