What Breaks Jessica's Heart About Motherhood

Jessica Simpson gets real about the challenges of motherhood in a new interview with People, in particular, finding the balance between her career and the responsibilities of being a new mother.

"On some of the days of Fashion Star, I'm awake before [my daughter Maxwell] is awake, and I'm not home until she's already back to sleep," she admits. "That's only happened about four times, but it makes the day awful. I definitely need to see my baby."

"I get really sad if I don't get to see her," she adds. "And then when Maxwell sees me, she just stares at me and touches my face. I can tell she missed me. That breaks my heart."

Jessica is also honest about the new fears she's developed.

"There are little things that you kind of obsess over. I never knew how protective I was until I had my own child. I'm already thinking about intruders coming into the house and what our escape route would be."

But perhaps most noticeably, the new role in her life has changed her signature style -- though she can still clearly have a little fun with it.

"I find myself going for more sophisticated looks, but I do think that's kind of trendy right now – just a classier looking woman," she muses. "I love to show off my curves, but being a mom, I guess I do it in a little bit more classy way, even though for Halloween I was a milkmaid –- but there are moments."
