Kristin Cavallari, Jay Cutler Welcome Son Camden!

Kristin Cavallari and fiance Jay Cutler welcomed their first child early Wednesday morning, she announced on Twitter. The beautiful baby boy's name?

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

Little Camden is the first child for the former star of The Hills, 25, and the Chicago Bears quarterback, 29, who got re-engaged in late 2011.

The couple split last summer, then reconciled ... then got pregnant!

Just last month, the reformed party girl gushed over her hubby-to-be's care-taking skills, along with declining mobility in her third trimester.

"Jay is currently making me lasagna... he takes such good care of me. Which is a good thing, because I can barely move," Kristin Cavallari tweeted.

Aww. She also said he's "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!"

We have no doubt. Congrats to Kristin and Jay!
