Kristin Cavallari ‘Excited For This Bun In The Oven’

'The Hills' star takes to Twitter to thank fans for support shortly after confirming she is expecting a baby with fiancé Jay Cutler.

When “The Hills” star Kristin Cavallari announced that she and her fiancé, football player Jay Cutler, were expecting their first child, longtime fans of the former MTV starlet began to send her lots of well-wishes.

It seems that all that love hasn’t fallen on deaf ears. “Thanks for all the sweet messages! We are so excited for this little bun in the oven,” she wrote, adding that she’s been using Twitter to deflect baby rumors in the weeks before announcing she was expecting. “I tweeted that I had margaritas a few weeks ago to throw ppl off cuz I had gotten a couple tweets about my pregnancy. I didn’t really drink!”

Meanwhile, Cutler is also thanking fans for all their support as the couple celebrates the next phase of their life together. “Thanks for all the tweets. We couldn’t be more excited,” he wrote. “We don’t usually comment on our relationship but for the record I never broke up with Kristin. It’s unfortunate some people are saying hurtful things during such a joyous moment in our life.”

One of her former “Hills” pals, Heidi Montag, also seems pretty excited. “Congrats on your life changing news!!!!” she tweeted. “You are going to be such an amazing mommy!! Sending you So much love!! Xoxo”

Heidi’s sister-in-law, Stephanie Pratt, spoke to UsMagazine.com about Cavallari’s good news, saying, “I am so excited for Kristin! They are going to be such a cute and fun family!”

Cavallari and Cutler announced the pregnancy on Sunday, two months after they announced they had gotten engaged for a second time. “We are thrilled to announce we are expecting our first child together,” the couple said in a statement to People.com when they confirmed the news. “It’s an amazing time in our life and we can’t wait to meet the new addition to our growing family.”

Cavallari was spotted over the weekend on the red carpet for the Cirque du Soleil “OVO” Celebrity Opening Night Gala, donning a skintight black dress. She once again was out and about on Monday in L.A., displaying her pregnancy glow.
