Kristin Cavallari had some perfectly appropriate post-Mother’s Day news to share today! The designer revealed that she and husband Jay Cutler are expecting their third baby. “The cutler crew just keeps on growin’!” she captioned a photo of herself with the couple’s two sons. Cavallari and Cutler, who’s quarterback for the Chicago Bears, are already parents to Camden, 2, and Jaxon, 1. No word yet on when baby #3 is expected to arrive.
