Kristin Cavallari Gets 'Game Day Kisses' From Her Son In Adorable Picture

Cavallari and Cutler are also parents to two boys, Camden, 3, and Jaxon, 1. in a previous interview with American Baby, the reality star opened up on why she was so happy to find out she'd be having a little girl. Part of the reason is due to her sons growing up with another female.

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

Cavallari also opened up on how each child has his or her own identity and it's important to be respectful of each one.

"My two boys are opposites," she said. "Camden was such an easy baby, Jaxon is more of our rebel wild child, but he's also a mama's boy. Our little girl will have her own personality."
