"I would love to have another baby - or twins!" fifth-time mom-to-be Joanna Gaines told PEOPLE in June, admitting husband Chip "thinks we're done"


According to Joanna Gaines, her husband Chip was singing a different tune just a few short months ago.

The Fixer Upper stars are currentlyexpecting their fifth child, they announced Tuesday — but the dad-to-be wasn’t always so sure about adding to their brood that also includes sons Duke, 9, and Drake, 12, plus daughters Emmie Kay, 7, and Ella Rose, 11.

“Chip thinks we’re done,” Joanna, 39, told PEOPLE in June, explaining of her own desires, “I would love to have another baby — or twins! The kids are always asking me, ‘Mom, can you have another baby?’ ”

“Emmie has never really wanted one, and now she’s like, ‘Okay. I want a brother or sister,’ ” added Joanna. “So I’m thinking that might be a sign.”

The change in plans was initiated in October, when the couple attended a concert so swoon worthy that “one thing led to another” naturally.

“You might recall a few months back.. the ever amazing, ever romantic @JOHNNYSWIM was in Waco. And they put on a little too romantic of a concert,” Chip, 43, tweeted on Tuesday.

“Anyways, one thing led to another, & we are officially pregnant. And I could not be more EXCITED! #5 #7ThePerfectNumber.”

In late October, the spouses appeared to mysteriously switch their stances on adding to their household. “We had four babies right before the show started, and then we’ve had zero babies since the show started,” Chip told Houston ABC affiliate KTRK. (The current season of Fixer Upper is the couple’s last.)

“For me, I’m really excited to go back and try to maybe … try to make some more babies,” he added, as his wife chimed in, “Maybe. We have different answers.”

But both parents-to-be are fully on board now — in fact, according to Joanna, her husband already has a hunch about the sex of baby No. 5.

“Chip swears he can already tell it’s a boy,” she captioned a Wednesday ultrasound video.
