DETAILS: Kristin Gives Birth To A Baby Boy

Kristin opened up about her new son:

“I like having this life that I’m responsible for,” Cavallari, 25, tells PEOPLE. “It’s exciting and so rewarding,” but the Laguna Beach and Hills reality star admits, “it’s also a little scary!”

While revealing how lucky she was to have a fairly easy pregnancy, Kris immediately realized how her life changed once she held baby Camden Jack for the first time. 

“It was the most incredible moment I’ve ever felt,” she explains. “With Camden, I’ve realized what really matters. We’re a family.”

Kristen and her NFL quarterback fiance are extremely proud parents and totally in love with their new son. Jay knows his baby boy is going to follow in his footsteps.

“He pointed out right away how big his feet are! And his hands were massive — he’ll sure be able to hold a football.”
