Kristin Cavallari = LA Party guurl =)

Kicking off her week with an evening out, Kristin Cavallari was spotted partying with some friends in Los Angeles last night (March 15).

The “Hills” babe looked super sexy in a black dress as she made her way around town with the paparazzi on her tail.

Earlier in the day, Kristin treated herself to some pampering with a manicure treatment at Delicate Nail Salon in Beverly Hills.

Miss Cavallari also stopped by Whole Foods supermarket to restock her pantry with plenty of healthy eats.
