Kristin Cavallari welcomes a son, 'Hills' co-stars send congratulations

Kristin Cavallari and her fiancé, Chicago Bears quarterback Jay Cutler, welcomed their first child, a baby boy, on Wednesday morning. The 25-year-old new mom announced the news on Twitter.

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

According to Us Weekly, not too long after she announced the arrival of her son, her former co-stars from The Hills were sending their congratulations via Twitter.

"Congrats!!!!!" Audrina Patridge wrote. "Can't wait to see Camden. So happy for you!"

"Congratulations on your new baby boy! One of life's greatest gifts! Enjoy mama! Oxxo," tweeted Heidi Montag. Her husband Spencer Pratt added, "Congratulations on Camden's birth! I'm free to be the Godfather if you need one!"

Camden is Kristin and Jay's first child. They announced they were expecting a baby earlier this year a few months after getting engaged for the second time. They briefly split last year. Now that they are proud parents, the next big step would be planning their wedding day.
