Kristin Cavallari
is expanding her family with a baby girl in November, but she may be reaching her limit.

“I’m not going to lie, three kids kind of scares me,” the 28-year-old told ET recently while promoting the Chinese Laundry Fall Fashion Campaign.

The Laguna Beach and The Hills star got candid about taking care of three young kids while her husband, Chicago Bears quarterback Jay Cutler, is knee deep in the NFL season.

“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.”

The former reality star credited her oldest child, 3-year-old Camden, for being “helpful.”

“He’s really sweet, so I’m just hoping that he’ll be my little helper and help me out as much as possible,” she said.

After having two boys, the shoe designer was excited about welcoming a little girl to the family.

“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 added.

One thing Cavallari won’t be announcing until the baby comes is the name, but she did open up about the unique inspiration behind it.

“There were rumors that I'm naming my daughter after a dog, which that's true -- I am,” she said. “But it's not that strange because people name their dog George and Harry now.”

“I did hear our daughter’s name at a baby store, the owner had named her dog this and she said at the time, ‘I wanted to name my little girl this name but I never had a little girl.’ And I remember thinking ‘God I love that name,’ and here we are three and a half years later.”

Cavallari also dished on her reality TV past, telling ET she talks to former Hills co-star Heidi Montag “all the time.”

"I love that they're still married," she said, "and they've sort of shut up all the haters, you know?"
