Kristin Cavallari (and over 700 other beach babes) on the shores of Miami on Saturday for Nivea/Cosmopolitan Magazine's second annual Bikini Bash. The scantily-clad ladies spelled out the words C-O-S-M-O and N-I-V-E-A with their bodies on the sand while Pulitzer Prize-winning photographer Vincent Laforet shot from a helicopter above. The final photo will appear in Cosmo's August 2009 issue.
