Kristin Cavallari Gives Birth to Baby Son Camden

One of reality TV’s most notorious “Mean Girls” is now basking in the joys of motherhood.

Kristin Cavallari and her fiance, Chicago Bears quarterback Jay Cutler, welcomed their first child — a son named Camden Jack — early Wednesday.

“We are thrilled to welcome Camden Jack Cutler into the world. He was born this morning weighing 7lbs 9oz. Everyone is doing great!” the former star of MTV’s Laguna Beach tweeted this morning.

Cutler,29, and Cavallari, 25, first became engaged last spring, but called off their wedding a few months later. Buzz of a reunion began to surface after Jay was spotted in the audience rooting Kristen on during her tenure on Dancing with the Stars. They got re-engaged last November and announced Kristin’s pregnancy in January.
