She’s definitely one of Hollywood’s hottest moms, and Kristin Cavallari hasn’t sacrificed any of her sex appeal while transitioning to a domestic goddess.

The “Hills” star is on the cover of Chicago’s Michigan Avenue magazine’s Fall Fashion issue, and in her interview she gushes over sons Jaxon and Camden.

Having welcomed Jax in May, Kristin shared, "He's doing great. He just started smiling about a week ago, which is the best feeling in the world. He is a good little baby. He's a happy baby, except that he's not a great napper, so I'm working on trying to get him to take better naps right now. He's sleeping well at night, which is all I can really ask for."

And it turns out having a second child is a much more manageable experience than welcoming the first baby- "It's a lot easier in the sense that you know what to do and expect, so you have a lot more confidence. But you have zero time to yourself now. Camden takes a nap at one o'clock, so when Camden's going down, Jax is just waking up to eat and play, so there's literally no time."

Cavallari also considers herself fortunate to have husband Jay Cutler as her parenting partner. "Jay is a great dad. He's incredibly hands-on, and he has been since day one. It's so sweet seeing him with Camden and Jax, and there's nothing sexier than seeing your husband as a great dad. I couldn’t ask for a better partner in this situation."
