Kristin Cavallari debuts her son Camden Jack a little over a month after giving birth to the baby boy. In a picture posted on PEOPLE, the former star of "The Hills" is beaming as she holds her bundle of joy in her arms. She wears a white tank top, while her boy looks adorable in a blue onesie.
"It was the most incredible moment I've ever felt," she raves. "With Camden, I've realized what really matters. We're a family." She continues to share the joy of becoming a first-time mother, "I like having this life that I'm responsible for. It's exciting and so rewarding," but admits, "it's also a little scary!"
Camden is her first child with fiance Jay Cutler. Recalling the first time the Chicago Bears quarterback met his son, the 25-year-old new mom gushes, "He pointed out right away how big his feet are! And his hands were massive - he'll sure be able to hold a football."
