Pregnancy agrees with Kristin Cavallari! The expecting shoe designer affectionately cradled her growing baby bump as she debuted her latest Chinese Laundry collection on Tuesday, Feb. 18.

The pregnant-again Hills alum, wearing black leather-like pants, a matching shirt and oversized blush-colored blazer, glowed with pride at the Kristin Cavallari by Chinese Laundry booth at Magic Market Week in Las Vegas.

Chicago Bears QB Jay Cutler's wife, 27, who later went on a mini shopping spree in Sin City, paired her professional attire with a pair of pointed-toe heels from her eponymous collection."I haven’t been able to wear my really high shoes anymore," she told Us Weekly back in December. "Luckily, all the shoes that I design aren’t as high as I used to wear, so these [pumps] actually are a piece of cake for me."

Between designing footwear and doting on 18-month-old son Camden, Cavallari has also been hitting the gym. The former reality star, who has been amassing likes from fans after posting numerous Instagram pics of her ever-growing baby bump, shared her latest gym selfie on Saturday, Feb. 15.

The reality TV alum announced in early February that she and her quarterback hubby are expecting another boy. "We couldn't be more excited!" she gushed via Instagram.
