Kristin Cavallari is Pregnant With Her Third Child

Reality star Kristin Cavallari and Jay Cutler are expecting another baby, the happy couple said on Monday.

Cavallari, 28, and Cutler, 32, are expecting their third child, the former reality star announced Monday on the Kristin Cavallari Official app.

Cavallari first teased the news on Instagram:

She then announced the news on her app.

"We're at it again! Thrilled to announce baby number 3 is on the way! The cutler crew just keeps growin'!" she said on the site, next to a picture of her in front of her two sons Camden, 2, and Jax, 1. In the picture on the app, she makes a heart around her pregnant belly.

In an interview with E! News, Cavallari said her first two were a breeze.

"I'm lucky," she said. "Both pregnancies have been really easy for me, I've just been really tired. It's just one of those things where I could literally sleep all day everyday but I'm snapping out of it a little bit now that I'm in the second trimester."

The former reality star said she is happy with her boys and how they look after each other.

"Camden is a really good big brother," she told Us Weekly. "He's very protective and very sweet, But he also gets a little upset when Jax tries to take his toys and messes with his stuff. He gets a little territorial with some stuff, so it's kind of funny."
