The Hills star, 28, showed off her growing bump on a spending spree in baby boutique Bel Bambini in West Hollywood (Friday 24 July).
Wearing a figure-hugging summer dress, the reality TV star-turned-designer was seen leaving the shop with a bag of goodies for her unborn baby.
No doubt, Kristin is stocking up on lots of pink!
Two weeks ago, she announced that she's expecting a baby girl.
In a cute picture with American footballer husband Jay Cutler, Kristin is holding a pink pair of tiny baby Converse in her hand.
Alongside the photo, she said: "The boys are so excited for a little sister!!!!!!"
Kristin and Jay are already parents to sons Camden, who turns three next month, and 13-month-old Jaxon.
She announced her third pregnancy in May, telling fans: "We're at it again! Thrilled to announce baby number 3 is on the way! The cutler crew just keeps on growin'!"
The stunning mum-to-be has told fans she is still working out throughout her pregnancy.
Sharing a picture from her gym earlier this week, she said: "Some of my favourite pregnancy workout moves."
And we thought being pregnant meant you could put your feet up!
