The blonde starlet - who rose to fame in Laguna Beach: The Real OC - was spotted running errands in sunny Los Angeles yesterday (7 April) while showcasing her oh-so-chic maternity wardrobe.
Gorgeous Kristin first opted for an electric blue minidress adorned with a white tribal print, complete with a pleated skirt which skimmed over her blooming baby bump.
The 27-year-old wore a pair of white peep-toe booties and a matching leather bracelet, while clutching her gold-clad iPhone in one perfectly-manicured hand.
And Kristin looked absolutely flawless on the beauty front too, sweeping her beachy locks over one shoulder and defining her chocolate peepers with heavy black liner.
But clearly not content with flaunting just one stunning outfit, Kristin soon changed into another stylish (yet slightly more comfy!) look as she headed to the shops later that day.
The stylista - who is already mother to Camden Jack, 22 months - nailed Cali cool in a monochrome striped maxi skirt, covering her bump with a simple white vest.
She added a touch of interest to her look by throwing on a denim gilet and shunned the heels, instead giving her feet a rest with flat black sandals.
And although her make-up remained the same, the starlet mixed things up in the hair department by pulling her locks back into a messy ponytail.
To finish? Glowing sunkissed skin, a mega-watt smile and her dazzling wedding ring, of course!
