Camden Jack Cutler details!

K-Cavs is officially a mama!

Kristin Cavallari and fiance Jay Cutler welcomed a baby boy Wednesday morning, she announced on Twitter.

"We are thrilled to welcome Camden Jack Cutler into the world," the former Hills star, 25, wrote. "He was born this morning weighing 7lbs 9oz. Everyone is doing great!"


Little Camden is the first child for Cavallari and the Chicago Bears quarterback, 29, who announced they were expecting back in January, two months after announcing their nuptials were back on. (They previously called off their engagement in July 2011.)


Cavallari's old Hills cohorts feted her baby-to-be at a late May baby shower in West Hollywood, with Heidi Montag and Spencer and Stephanie Pratt stopping by the bash. Cavallari "was glowing and gorgeous," a source told Us. "She looked so happy!"

In late July, the reformed party girl gushed over her sweet hubby-to-be's caretaking skills -- and her lack of mobility in her third trimester. "Jay is making me lasagna...he takes such good care of me. Good thing, because I can barely move," she tweeted.



Earlier this year she told Us that Cutler is "gonna be a great dad! He's so cute with kids...He's good with my little dog, so he's gonna be really, really cute with kids!"
