Kristin Cavallari is PREGNANT!

Parents-to-be Kristin Cavallari and Jay Cutler at Opening Night Of Cirque du Soleil's 'OVO' over the weekend.

It looks like a feisty blonde bridesmaid is going to steal the show at Stacie The Bartender's wedding. Former "Hills" star Kristin Cavallari has confirmed she's expecting a child with fiancé Jay Cutler only six months after the couple called off their wedding and seemingly broke up for good. Cavallari and Cutler have since reconciled and confirmed the wedding is back on, and now, there will be one more witness to what's sure to be a jam-packed ceremony.

"We are thrilled to announce we are expecting our first child together," the TV star and the Bears QB told People Sunday. "It's an amazing time in our life, and we can't wait to meet the new addition to our growing family." And we can't either! If the kid can dance as well as she can (BS "DWTS" eliminations be damned...) or has his precision with pigskin, the littlest Cutvallari will be set for life.

While the news was surely a shock to K-Cav's former "Hills" costars, congratulations came from one very unexpected source on Twitter--Kristin's on-air enemy, Audrina Patridge, who tweeted "@KristinCav congrats Kristin!!!:) gonna be such a cute baby xoxo" shortly after the story broke. Sounds like some solid hatchet-burying, Auntie Audrina. "Jersey Shore" star Snooki chimed in, too, tweeting "@KristinCav So cute, congrats on your baby news!!!!!" K-Cav thanked everyone for their well-wishes with an online confirmation that she's ready to start a family: "We are so excited for this little bun in the oven," she tweeted.

+ What do you think of Kristin's BIG announcement? Is she ready for life as a full-time momma? As long as she's still committed to not throwing pumpkins at kids, we think she'll make an excellent parent. Congrats, K!
