Congratulations are in order for Kristin Cavallari and Jay Cutler.

The Hills alum, 28, and the Chicago Bears quarterback, 32, are expecting their third child, she announced Monday on the Kristin Cavallari Official app.

“We’re at it again! Thrilled to announce baby number 3 is on the way! The Cutler crew keeps on growin’,” the Laguna Beach star captioned an image with her sons Camden Jack, 2, and Jaxon Wyatt, 1, sitting in a wagon.

Just before making her big announcement, Kristin shared a teaser on Twitter.

“I’m announcing big news on my app today! Search Kristin Cavallari in the App Store,” she wrote.

Last week, the reality star-turned designer shared birthday wishes for her youngest son.

“Before we had children, Jay and I both wanted four,” she has said. “Now we’re thinking three, but we’re just going to have to see how it goes. Right now the last thing on my mind is having another baby, but it is a ton of fun.”
