She’s thrilled about expecting her second child and Kristin Cavallari showed off her growing midsection via Instagram over the weekend.

On Saturday (January 18) the “Laguna Beach” babe headed over to her local fitness center for some workout fun, and of course she brought her camera phone.

Sporting an all-black ensemble, Kristin snapped a shot of her baby belly and added the caption, “Gym selfie… baby bump getting big!”

As for the gender of the bun in the oven, Cavallari previously told press, "I would love to have a little girl, but if I had another boy, that would be great too."
