The on-again, off-again couple are bringing a baby into the mix

Now that it's become clear that Kristen Cavallari's fiance Jay Cutler isn't running for the hills, the newly happy couple are starting a family.

Though the Chicago Bears quarterback, 28, and the former Hills and Laguna Beach starlet, 25, called off their engagement in July, it was only a few months later that they got back together again, which Cavallari confirmed at the time with a simple tweet saying, "Jay and I are engaged again :)." Later she addressed the split. "Sometimes, in order for things to get better, they have to end — even if it's momentarily."

"We are thrilled to announce we are expecting our first child together," Cavallari told People on Sunday. "It's an amazing time in our life and we can't wait to meet the new addition to our growing family." No word yet on if the couple have set a date for their nuptials, or if Cavallari will need to let out her dress at the time.
