The former Hills and Laguna Beach star has been looking fantastic ever since announcing in October that she is expecting her second child with husband Jay Cutler.
Kristin, 27, highlighted her baby bump in an Emilio Pucci dress on Wednesday (12 March) as she promoted her new TV show Fabulist.
She's wearing a pair of shoe boots from her own Kristin Cavallari by Chinese Laundry collection.
Fabulist is a new weekly E! show hosted by Kristin and featuring a panel of experts, which focuses on the latest beauty, fashion and lifestyle trends.
It starts in the US on 17 March.
Kristin announced her role on the show back in February, telling fans: "THRILLED to finally announce I'll be hosting a new half hour show called The Fabulist on E! with the beautiful @orlyshani. We will discuss the top trends in fashion, beauty, and lifestyle."
She's been juggling promotion for the programme with her pregnancy. Kristin and her American football hubby Jay are also parents to son Camden, who was born in August 2012.
