The couple already has a son, Camden, who turned one in August.
The Hills alum recently talked about her desire to have another baby.
In September she told E! News that she and Cutler were already trying to grow their brood.
"We want to have a second sooner rather than later," the 26-year-old told E! News at a Junk Food Vintage NFL event in New York. "We're working on it!"
This time around, the reality star and her Chicago Bears quarterback hubby are hoping for a girl.
“Obviously, I want a little girl, but if I had another boy I would be so excited as well,” she shared.
