Bump in the road!

Sporting a blue blazer and ruched shirt, mom-to-be Kristin Cavallari gave us a glimpse of her budding belly while walking her pet pooch around her Chicago neighborhood.

The reality star recently revealed she and her husband, Chicago Bears quarterback Jay Cutler, are expanding the family den and planning for the arrival of a sibling for son Camden Jack, 15 months.

“Thank you for all the love!! We are so excited for Camden to be a big brother!” Cavallari, 26, posted on her Instagram account.

With football season in full swing, the soon-to-be family of four has been spending time at their home in the Windy City — giving Cavallari plenty of girl time.

“It’s easy to get wrapped up in your career and have that be your only focus, and I want my marriage to work and last — and family comes first,” she has said.
