I’m not into Halloween but I do enjoy seeing people dressed up. This year Kim Kardashian and Heidi Klum served fierce halloween costumes Saturday night. Kim K sported her look at the Midori Green Halloween Bash at Lavo in NYC. She was the infamous Poison Ivy character from the Batman series, played by Uma Thurman. While Heidi Klum sported her look at her 13th annual Halloween Bash at Tao in Vegas. Trick or treat???
