Did Khloe Kardashian dye her hair purple or is Rob Kardashian playing with our emotions?

Rob Kardashian, oh Rob Kardashian, you do know how to tease us on Instagram, don't you?

First the brother Kardashian posts sneaky selfies of himself, which we're not sure if they're current or not, then he posts cute pictures of his niece North West, with her dad Kanye, and now he's shared - AND QUICKLY deleted - a snap of his older sister Khloe Kardashian sporting PURPLE HAIR.

It appears Khloe has gone fully purple, unless Photoshop has been a helping hand in Rob's creative Insta-skills.

Rob, 28, shared the image to his 3.6 million Insta-followers before taking it down and has since posted homage to Bill Murray to celebrate the actor's birthday.

Then Khloe posted this - no purple hair visible:

Just hours prior to Rob's post, the Keeping Up With The Kardashians star shared that she was in the gym.

Rob and Khloe's younger half-sister Kylie Jenner is the queen of different coloured hair - Has Khloe now followed in her footsteps?

There have been rumours recently that Khloe didn't download Kylie's new App, in fear of the competition.

Has Khloe dyed her hair to rival Kylie and get more followers? What do you think? (If Khloe has dyed her hair that is).
