Pregnancy first-timer Kristin Cavallari’s belly is most certainly growing and she’s not afraid to show it off. The glowing reality starlet and mom-to-be stepped out for a few Oscar festivities Sunday night, with her small baby bump on full display.

Cavallari admitted via Twitter that she was surprised at how big her belly had grown, tweeting about her baby bump just hours before the Academy Awards. “My stomach literally grew double overnight!! This belly came out of nowhere!” she tweeted.

In January, the former Laguna Beach and The Hills  star and her fiance, Chicago Bears quarterback Jay Cutler, made the announcement that they were expecting, and Cavallari said that they were delaying their wedding until after the baby arrived.

“I’m not even looking for a wedding dress right now,” she stated in an interview with Celebuzz in early February. “I’m pregnant. So I’m not going to try on wedding dresses.”
