They've got a new project in the works!

Fixer Upper stars Chip and Joanna Gaines are expecting their fifth child, they announced in an adorable Instagram. "Gaines party of 7.. (If you’re still confused.. WE ARE PREGNANT @joannagaines,” they captioned a photo of her baby bump.

The couple are already parents to children Drake, 12, Ella, 11, Duke, 9, and Emmie Kay, 7.

The pair shocked viewers when they made the decision to walk away from their wildly popular HGTV show to focus on family.

"We had four babies right before the show started and then we’ve had zero babies since the show started. For me, I’m really excited to go back and try to maybe … try to make some more babies," Chip told ABC News back in October.

Building the perfect nursery should be no problem for them!
