Kristin Cavallari Says She Gets 'More Breakouts' During Pregnancy

Cavallari and Cutler are also parents to their one-year-old son, Jaxon. The reality star is currently pregnant with the couple's third child who is expected to be born any day now. 

Earlier this week, Cavallari added a photo of herself where her pregnant belly is in plain sight and she wrote that she's ready for child number three "whenever you are baby."

Cavallari previously spoke with American Baby about how each of her children has their own identity and it's important to appreciate them all.

"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. 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."
