Kristin Cavallari Admits She & Husband Jay Cutler Go to Therapy: "It's Been Extremely Beneficial"

The pregnant star, who's expecting her third child with the NFL quarterback, isn't afraid to admit that the couple has to work on their marriage to stay on track.

"I'm not ashamed to say that Jay and I consistently go to therapy, because it's been extremely beneficial for our relationship," she says in the December/January issue of American Baby. "For example, when you're fighting you should never place blame on your partner by saying, 'you do this' or 'you do that.' You should say how those actions make you feel. It goes a long way."

The "Hills" star is excited to welcome another girl into the household, and she says her little one will "steal Jay's heart" and be good for her boys, Camden, 2, and Jaxon, 17 months.

"I'm excited for the boys to grow up with a sister," she explains. "I think it will help them to better understand and respect women."

The proud mama can't help but gush about her sons, admitting that her boys are opposites. "Camden was such an easy baby. Jaxon is more of our rebel wild child, but he's also a mama's boy," she says. "Our little girl will have her own personality. I know I can't change who they are. It's important to let kids be themselves and to let them make mistakes. Self-discovery goes a long way."

The 28-year-old star realizes what she's getting into the third time around. "Having an infant is stressful, and I know I won't get a lot of sleep initially, but it will be worth it,” she says. “Jay and I want our kids to be close in age, so they can have a tight bond. And we'll get the diaper phase out of the way!"

We can't wait to see the boys with their baby sister!
