The former Laguna Beach and Hills star was snapped carrying little Camden into Lemonade restaurant for a bite to eat on Tuesday afternoon (30 July).
Kristin looked stunning in skinny jeans, a simple white T-shirt and a leather jacket, teamed with black heels. We're loving the pop of colour with her scarf too.
With such a knack for putting together fabulous outfits it's no surprise Kristin has been turning her hand to the design world lately, most recently launching a shoe line in collaboration with Chinese Laundry in Chicago.
She also has another project in the works, tweeting yesterday: "So excited to design my first ever collection with @junkfoodtees and NFL Women's Apparel during @nyfwstyle360! #junkfoodnfl."
Aside from success in her professional life, the reality star has been on cloud nine in her personal life this year after marrying NFL player Jay Cutler - the father of her son - in a fairytale ceremony in Nashville in June.
