sunglasses Kristin Cavallari elevator the hills

Here's the thing about Kristin Cavallari - she may not be the most entertaining, scandalous star, but she's always so sweet to our photogs, we can't help but gush over her every time we see her!

Yesterday we spotted KC at a medical building in Beverly Hills, and even though she was barefaced and wearing workout clothes, she flashed her pearlies for the paps. What a trooper!
