Camden Jack is going to be a big brother! Kristin Cavallari and husband Jay Cutler are expecting their second child together.

UPDATE: "Thank you for all the love!! We are so excited for Camden to be a big brother!" she expressed to fans via Twitter, confirming the news Wednesday afternoon. The pregnant-again Hills alum, 26, and the Chicago Bears quarterback, 30, are already parents to their 14-month-old son. They tied the knot back in June of this year after two and a half on-and-off years of dating. Now a fashion designer with a shoe line for Chinese Laundry, Cavallari has been hinting for months that they were anxious to expand their brood.

"It's funny — before we had Camden I was like, 'Yeah, four kids, no problem!'" Cavallari told local Chicago news station, WCIU, during an Oct. 11 appearance. The designer mom also told WCIU that she and Cutler were "working on" baby no. 2.

"We're doing all the necessary things to get pregnant," she teased. While the gender of the baby is not yet known, Cavallari revealed to Us Weekly in September that she would "love to have a little girl…But if I had another boy, that would be great, too."

E! News first reported Cavallari's second pregnancy. The Cutler clan splits their time between Chicago, L.A. and Nashville.
