Jay Cutler's fiancé Kristin Cavallari gave birth to the couple son's a little more than a month ago, and the bundle of joy ventured into the outside world for the first time this week.

Photographers spotted Cavallari pushing her new son Camden Jack Cutler in a stroller around Chicago, where she and the Chicago Bears quarterback live.

Cutler and Cavallari welcomed their new baby boy to the world on Aug. 10, eight months after the couple announced the pregnancy in January.

The photos taken this week don't give fans a peek at little Camden, but Cavallari said on her Twitter account that a better look is coming soon.

"Doing a photo shoot today with the baby. Can't say which magazine yet but I'll let u know when it comes out :)" she tweeted Sept. 7.

The former star of "The Hills" also shared with her followers about how excited she was to become a mother.

"Being a mom is the most incredible feeling. I am so in love with this little boy!" she wrote.

Cutler and Cavallari first began dating in August 2010 and got engaged in April 2011. Cutler called off the engagement in July of that year, but by November, Cavallari announced the engagement was back on.
