Kristin Cavallari’s baby bump is getting bigger! The former Hills star, 26, announced she was pregnant with baby number two just a little over a month ago, and she’s already showing. Kristin’s already showed off her bump on Twitter, and on December 3, her belly made its big red carpet debut.

The former reality star, who is already the proud mama of 15-month-old son Camden Jack, posed for photographers at the 27th Annual Footwear News Achievement Awards in New York City.

Wearing a tight black lace cocktail dress that showed off her baby bump, Kristin placed her hand gently over her belly as the camera’s clicked away. Seen from an angle, her bump is definitely visible. But from the front angle, Kristin’s belly is harder to identify. After all, she’s still not too far along quite yet.

Since this was a footwear-themed event, Kristin was sporting a pair of heels of her own design — the black suede "Copertina" heel from her Kristin Cavallari by Chinese Laundry line — though the starlet lamented to Us Weekly that pregnancy has made it so she hasn’t been able to wear her “really high shoes” anymore.

As she’s previously mentioned, Kristin her hubby, NFL quarterback Jay Cutler, don’t plan on publicly revealing the sex of their baby before the birth. However, the couple does want to know for themselves and Kristin has come up with a unique way for them to find out.

"I’m going to have my doctor write it on a note, and put it in an envelope, and we’re going to open it on Christmas" she told the mag. Sounds like the perfect gift!
