Kristin Cavallari and Jay Cutler are proud parents to a bouncing baby boy named Camden Jack Cutler.
The former "Laguna Beach" and "The Hills" star tweeted the happy news Wednesday morning.
This is the first child for the engaged couple.
Cavallari and Cutler started dating in the fall of 2010 and got engaged in April 2011. Though the couple broke off their engagement in July, they reconciled and announced in November they were engaged once again.
Since then, we've seen Cavallari and her growing baby bump move from LA to Chicago, where Cutler plays quarterback for the Chicago Bears. In fact, it was one of Cutler's teammates who accidentally spilled the beans that the couple was expecting a baby boy. Whoops!
Cavallari hasn't been shy about her pregnancy and opened up to Glamoholic in March.
"Your motherly instincts naturally kick in," she said about learning she was expecting. "We weren't trying to have a kid but we weren't not trying, we left it up to fate. I knew there was a possibility but I was really excited! Even if you are trying, just to see a positive result is shocking!"
Though they plan on walking down the aisle at some point, the former "Hills" star and "Dancing With the Stars" contestant told Glamoholic that they might try to have another kid before tying the knot.
"We're talking about the possibility of having another kid right away and then getting married so we can have 2 kids close in age," she told the magazine. "We want 4 kids, so we're thinking maybe have one more, then get married, then have two more but we'll see, it all depends on how the first one goes."
No matter when she gets married, Cavallari has the support of her old friends, including her former "Hills" co-star Heidi Montag, who recently gushed about the mom-to-be to Us Weekly.
"[Cavallari] is the most beautiful pregnant woman I've ever seen and I'm very proud of her," Montag said. "I think she's gonna be the best mother ever."
