Or has she? It seems pretty extreme...
Then again, Kim does seem keen on reinventing herself of late, vowing to lose loads of weight and update her image.
So perhaps she really has hit the bleach bottle a la Tulisa.
Or...
Maybe it's for her super amazing mermaid Halloween outfit?

OK, we tricked you - but then again it is the time of Trick or Treat so can you blame us?
Kim posted the snap on her Twitter feed with the message: 'Sneak peak' before posting a picture of the finished outfit a few hours later.
Kim and Kanye are American so don't do the whole 'scary fancy dress' thing, rather opting to dress up as, well, anything.
Taking a leaf from the Mean Girls book of Halloween dressing, Kim dressed up as a sexy mermaid.
How, er, spooky eh?
And her boyf Kanye was happy to get in the Halloween spirit, dressing up as her very own Captain Eric!

Kim posted the snap on Twitter with the message: 'Me & my captain!'.
However, we reckon rolling up your trousers and putting on some nautical stripes hardly a Halloween costume makes.
While we doubt Kanye is the biggest fan of fancy dress, he could have at least invested in a Captain Birdseye hat.
