Reality TV star Kristin Cavallari and NFL quarterback Jay Cutler are having a baby.

“We are thrilled to announce we are expecting our first child together,” the pair tells People. “It’s an amazing time in our life and we can’t wait to meet the new addition to our growing family.”

The big news comes as something of a surprise. In July, the “The Hills” villain and Chicago Bears star abruptly called off their engagement, just days after Cavallari appeared in the pages of Life & Style magazine, posing in wedding gowns. But the pair reunited in November.

“This time it’s official,” Cavallari tweeted at the time. “Jay and I are engaged again :)”

Soon after, Cavallari explained the split and subsequent reconciliation to People.

“Sometimes, in order for things to get better, they have to end – even if it’s momentarily. That was the case with us,” she said. “We didn’t break up because of love lost. We loved each other just as much as we always did when we weren’t together.”

Cavallari’s friends from her reality TV days have taken to Twitter to congratulate her.

“Congrats on your life changing news!!!!” writes Heidi Montag. “You are going to be such an amazing mommy!! Sending you So much love!!”

Audrina Patridge adds, “Congrats Kristin!!!:) gonna be such a cute baby xoxo.”
