Batman villainess Poison Ivy seems to be the Halloween costume choice for two sexy celebs. Both Kim Kardashian, 31, and Julianne Hough, 23, chose to go green, stepping out in the form-fitting getup. 

The Footloose star posed alongside her brother Derek Hough who wasn’t so into the spirit, not appearing in costume. The Dancing with the Stars, 26, pro tweeted a pic of him and his sis, writing: “I dont think I got the memo … Happy Halloween !!!” Meanwhile, Julianne hinted about her bad girl costume, tweeting

“Halloween Costume Hint: Wearing my RED wig that I wore in Burlesque, but… my character is from another movie! :)”

Meanwhile, Kim K. also looked “Poisonous!!!”

She tweeted her appreciation for her costume team, writing: Seriously @MonicaRoseStyle @robschepp @jOYCEBONELLiworked their MAGIC on my Halloween costume this year! They did their THANG!!!
