The current season of Fixer Upper is going to be the last, as Chip and Joanna Gaines are ending the show to concentrate on other projects. And it looks like one of those projects is a new baby! Chip Gaines teased a big announcement before the latest episode of Fixer Upper, and this week they announced on Instagram that they're expecting baby number five.

"Gaines, party of seven," he wrote alongside a photo of himself and Joanna. "(If you're still confused.. WE ARE PREGNANT.)"

Joanna Gaines is pregnant, and Chip is extraordinarily excited. Back in October he told ABC News that he was looking forward to using the downtime after Fixer Upper ends to "make more babies."

"We had four babies right before the show started and then we've had zero babies since the show started," he said. "For me, I'm really excited to go back and try to maybe … try to make some more babies."

The couple already has four kids: Drake, Ella, Duke, and Emmie Kay. The kids range in age from 7 to 12, and they've been growing up in front of viewers for the past five years, often making cute appearances on Fixer Upper.

With the fifth baby on the way, Chip Gaines has clearly been chomping at the bit to announce this pregnancy. Before the latest episode, he was posting little hints about the "big reveal" all over social media.

Now that the news is out, Joanna Gaines even posted an ultrasound video to Instagram. She says Chip is sure it's a boy.

Whatever the new baby is, it will certainly be growing up in a great house surrounded by a ton of very excited parents and siblings. And even though Fixer Upper is ending, the Gaines aren't really going away, so we can all look forward to some cute baby pictures to look at in a few months.
