Kristin Cavallari will now be carrying a baby in her arms instead of her belly.

The former The Hills star has announced she and fiance Jay Cutler have welcomed their first child.

"We are thrilled to welcome Camden Jack Cutler into the world. He was born this morning weighing 7lbs 9oz. Everyone is doing great!" tweeted Cavallari of her new baby boy, who was born Wednesday morning.

Cavallari and the NFL Chicago Bears quarterback revealed they were expecting a child together in late January but wanted to wait to wed until after the baby's arrival.  

The couple got engaged in April 2011 after just seven months of dating and reportedly split that July when Cutler dumped her, leaving her "absolutely devastated" and "in shock."

Cutler and the 25-year-old reality TV star reportedly began reconciling in September of that year and got re-engaged in late November. The announcement came just one week after Cavallari, who had also competed on the thirteenth season of Dancing with the Stars, had denied a re-engagement.
