Kristin Has Every Reason To Smile

I love Hills hottie Kristin Cavallari - I always thought she had 100 times the personality that Lauren Conrad did, and she ALWAYS smiles for photographers when she's out and about.

Yesterday we caught Kristin shopping with some pals at Planet Blue in Malibu, and after a successful retail therapy sesh, Kristin was in a fabulous mood. But what was she doing here - hailing a cab? The Hills girls don't have to take taxis?! Spend that reality TV money honey!
