Kristin Cavallari and Fiance Jay Cutler Expecting A Child

Reality television star Kristin Cavallari and her fiancé, NFL quarterback Jay Cutler, are expecting a child, People magazine reported.

"We are thrilled to announce we are expecting our first child together," the pair told the magazine exclusively. "It's an amazing time in our life and we can't wait to meet the new addition to our growing family."

This is the second engagement for the couple. Cutler, 28, began dating the reality star and "Dancing With the Stars" contestant in the fall of 2010. In July 2011, "The Hills" star and her Chicago Bears boyfriend called off their first engagement, but announced again in November they would indeed tie the knot.

"This time it's official. Jay and I are engaged again," Cavallari, 25, tweeted about her on-again engagement.

Cavallari has previously dated Stephen Colletti, her "Laguna Beach: The Real Orange County" co-star and her "The Hills" co-stars, Justin Brescia and Brody Jenner.

Kristin's "The Hills" co-stars Heidi Montag and Audrina Patridge have since sent their best wishes to the couple via Twitter.

"Congrats Kristin!!!:) gonna be such a cute baby xoxo," Patridge tweeted.

"Congrats on your life changing news!!!! You are going to be such an amazing mommy!! Sending you So much love!! Xoxo (sic)," Montag wrote.
