Kristin Cavallari Shows Off Baby Bump Before Oscar Festivities (PHOTO)

Pregnant Kristin Cavallari's belly is definitely growing and she's not afraid to show it off. The reality star and mom-to-be stepped out for some Oscar festivities Sunday night, with her small baby bump on full display.

Even Cavallari admitted that she was surprised at how big her belly had grown, tweeting about her baby bump just hours before the Academy Awards.

Good thing her dress still fit!

In January, Cavallari and her fiance, Chicago Bears quarterback Jay Cutler, announced they were expecting, and Cavallari revealed that they were putting their wedding on hold until after the baby arrives.

"I'm not even looking for a wedding dress right now," she told Celebuzz in early February. "I'm pregnant. So I'm not going to try on wedding dresses."
