Kim Kardashian switched her trademark chocolatey locks for a long blonde 'do last night, while hitting a fancy dress party with booze brand Midori.
Sparking a lot of mixed feedback on Twitter - some people obviously take Kim's hair very seriously indeed - the star Instagramed a sneak peek of her new look, before hitting the bash.
Later revealing that was dressed up as movie mermaid Splash - who actullay, had a red tail rather than green but whatevs - Kim posted a pic of her with Kanye West, who seemed to have come as a sea captain.
Scary Halloween combination? Errmm...
Though the blonde hair doesn't look too bad up close, it's not great from a distance is it. Yikes!
We're hoping Kim doesn't make a habit of this wig. Are you?
