Holy sexy Halloween costumes, Batman!
On the East Coast, Kim rocked a supersexy strapless minidress covered in ivy with glittery platform pumps, a bright red wig and gold bangles when she hosted a bash at Lavo in New York City, sans hubby Kris Humphries.
Julianne had the same idea for a Halloween bash back in Hollywood. The Footloose star tweeted a photo of herself with big brother Derek Hough in an ivy-covered corset top with skintight green lamé pants, green cuffs and a brown wig.
"Halloween Costume Hint: Wearing my RED wig that I wore in Burlesque...but my character is from another movie!" she teased.
So which star had the better Batman villainess costume? And can either babe hold a candle to Uma Thurman's Poison Ivy from 1997? Check the pic below and then weigh in!
