Former Hills and Laguna Beach star Kristin Cavallari announced on Sunday that she is pregnant with Chicago Bears quarterback Jay Cutler's baby.

We are thrilled to announce we are expecting our first child together, 25-year-old Cavallari told People. It's an amazing time in our life and we can't wait to meet the new addition to our growing family.

Cavallari and Cutler, 28, began dating in the fall of 2010 before announcing their engagement in April 2011. The couple had a small hiccup in their relationship when they called off their engagement three months later due to XX. However, after a period of reconciliation, Cutler and Cavallari renewed their engagement in November.

Sometimes, in order for things to get better, they have to end - even if it's momentarily, Cavallari told People back in November while she was competing on Dancing with the Stars.

Cutler and Cavallari made their first public appearance together since announcing their re-engagement on Friday at a Cirque Du Soleil show in Santa Monica. Kristin Cavallari was weight a knee-length black sequin-embellished dress.

Ovo was amazing!!! The performances were insane!! Cavallari tweeted on Saturday.

Kristin Cavallari has not announced her pregnancy on her Twitter account yet, but her rep from EMC-BOWERY confirmed the news to People.
