The reality star announced in July that she and her husband were expecting their first child together. Houska already shares daughter Aubree, 7, with her ex-boyfriend Adam Lind.

"We’re really excited and Aubree is pumped to be a big sister," Houska told MTV News at the time.

Houska and DeBoer began dating after meeting at a gas station in 2014 and got engaged in November 2015. They tied the knot in October.

"So as most of you already know, yesterday Cole and I got married in a tiny ceremony just with our parents and siblings," Houska tweeted after the wedding. "Next year, once our baby is here and able to be part of it, we will have a big ceremony and reception with our friends/extended family."
