'Laguna Beach' Star Kristin Cavallari Expecting Third Child: What Scares Her?

Laguna Beach star turned shoe designer, Kristin Cavallari, is expecting her third child in just a few weeks. In a recent interview with Entertainment Tonight, the confident mom of two shared that she is feeling nervous about raising three children under the age of four.

"I'm not going to lie, three kids kind of scares me," she said.

Cavallari's NFL star husband and Chicago Bears quarterback, Jay Cutler, travels often during football season, which leaves the young mom at home to raise their quickly growing brood.

"I'm going to be alone with three children a lot, but we're just going to figure it out," Cavallari said. "I'm not the first mom to do it. I'm certainly not the last."

Cavallari has shared several photos of she and her two younger boys, Jax, 17 months and Camden, 3, on Instagram and is excited to be welcoming a baby girl.

"Everyone's really excited. I'm already getting the nursery ready!" Cavallari said. "I didn't think I would be a big 'pink' girl but everything is pink. There's a chandelier. I'm getting all the pink and purple clothes."

"I'm just excited to have a little mini me and now I have someone that I can give all of my stuff to, which is great," she continued.

On Wednesday, Cavallari posted a serene black and white pregnancy photo on Instagram with the caption, "It's hard to believe I will be a mom of 3 in just a few short weeks. I owe so much to my babies...they have changed me in so many ways for the better."

She is also celebrating her new book, Balancing in Heels. The book, which will be released in March 2016, is about her journey to becoming a successful young woman as well as the changes she has made to live a healthier and happier life.
