Don't mess with Kim Kardashian this Halloween!

The reality star decided to take the comic book villain route this year and dressed as Batman nemesis Poison Ivy for the Midori Green party in New York.

"Glamming up for my Midori Halloween party at Lavo tonight! I have bright red hair! OMG this is kray!" she tweeted before heading out.

While husband Kris Humphries didn't make it the party, Kardashian's best friend Jonathan Cheban kept with her Batman theme and dressed up as Batman sidekick Robin.
