Pregnant 'Fixer Upper' star Joanna Gaines reveals her daughter's genius business idea

Chip and Joanna Gaines aren't the only business moguls in the (very large) family.

The Fixer Upper couple's 11-year-old daughter, Ella, is becoming quite the entrepreneur.

"Her new summer business is selling baked goods at the office when she goes to work with me," Joanna wrote in a post on Instagram on Thursday night. "Tonight we stayed up late and she made Aunt Opal’s banana pudding and the chocolate chip cookies from my cookbook."

"She's going to make a heck of a business woman," Joanna added.

Joanna and Chip -- who are also parents to Drake, 12, Duke, 9, and Emmie Kay, 7 -- are expecting their fifth child in a matter of months.

The home renovation duo recently confirmed they're expecting another boy -- and given their tradition of giving the boys names that start with the letter D and girls names that begin with E, Chip has been brainstorming.

"Is that a secret? I don't know. That might not even be allowed on Twitter," Chip revealed in a Twitter video on March 8. "You better keep that to yourself, dude. But listen to me: It's a little boy, and I need a 'D' name. And so far, all I can come up with is Dragon. [Joanna was] like, 'You are not calling that baby Dragon!' Can you help me?"

After five years on air, Chip and Joanna farewelled their hit reno show in April.

Following the episode, Joanna tweeted, "We love you guys!!! Thank you for being a part of this journey with us. What a ride."
