Kristin Cavallari’s Cosmo Bikini Bash

What do you get when you add hundreds of babes in bikinis, a hot reality star, and a chick magazine? Eye candy overload!

Laguna Beach alum Kristin Cavallari hit Cosmopolitan Magazine’s Second Annual Bikini Bash in Miami yesterday for the country’s largest swimsuit photo shoot. Hundreds of scantily clad women spell out the word C-O-S-M-O for an aerial photo to run in the mag’s August issue.

The bubbly blonde wore a green bikini with light denim shorts. Her upcoming flick, Van Wilder 3 is slated for release on DVD on Tuesday, March 17th. (Who knew there was a third one?!)

Despite being a gal known for her party girl persona, Kristen wants to be taken seriously. She tells the, “I want to go dark — dye my hair and do something really dramatic. Kind of the way Angelina Jolie did in Changeling, when you go into yourself and really bring it.”

If by “really bring it” she means looking strung out and searching for a lost child, she could simply hold up a mirror. Ouch!
