Now Kristin Cavallari is officially a mom! Yesterday morning Kristin gave birth to a baby morning, and she announced it on Twitter just hours after the birth: "We are thrilled to welcome Camden Jack Cutler into the world", the former reality star wrote. "He was born this morning weighing 7lbs 9oz. Everyone is doing great!", she continued. Camden is the first child for both Kristin and the father, her fiance Jay Cutler. They announced she was pregnant back in January, which was just months after they reconciled after a short break up. Congrats, Kristin and Jay! We hope you'll be a happy little family! (wonderwall)
