Kristin proved just what a yummy mummy she is when she stepped out to run errands in the sunshine city while wearing tight white skinnies and a beige loose top.
The US reality star teamed her outfit with a brown designer handbag and tottered along the pavement in a pair of nude strappy wedges.
Audrina, meanwhile, was snapped at the Thirst Project 4th Annual Gala while showing off her perfect pins in a body-hugging bandage dress with sheer detailing on the bust.
She was also wearing nude heels and completed her look with a chain-style belt and loosely curled hair, which was swept to the side over her shoulder.
Although Kristin was rocking daytime chic and Audrina nighttime elegance, we think both Hills ladies deserve a thumbs up for looking so fab!
