Bumping her way through LAX, Kristin Cavallari arrived on a flight in Los Angeles on Tuesday (November 19).

The "Hills" star dressed her budding belly in a black top and matching leggings along with a beige sweater as she headed outside.

Confirming the happy news on Twitter late last month, the 26-year-old tweeted on behalf of herself and NFL hubby Jay Cutler, "Thank you for all the love!! We are so excited for Camden to be a big brother!"

Though she's often traveling as a busy fashion designer, the working mom is clear on her priorities, telling Coco Eco, "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."
