Katy Perry picks orange as her break up hair colour, John Mayer has a lot to answer for!

Katy Perry's multicoloured strands are as sensational as her songs she's rocked pink, blue, purple and black hair making her the most biggest celebrity hair chameleon.

But instead of a more subtle shade Katy Perry has gone for a fiery orange as she sits pretty on the cover of French magazine, L'Officiel.

And if that isn't a great post break-up comeback we're not sure what is!

Clad in a peach dress complete with black floral accents by Louis Vuitton, the songstress channels a little Florence Welch.

The look was completed with a natural shade over her eyes and pink blushes swept high up on her cheekbones adding an androgynous style to the shot.

Katy Perry has been spied rocking a black bob recently, so it's not thought the orange make-over was a permanent affair but it certainly puts her rumoured ex, John Mayer in his place.

It's believed that last week the actor parted ways with the singer following their fling this summer and left her a little emotionally bruised.

A source told Radar Online: "She held off from his advances for the longest time, but he laid on the charm thick and promised her he was a changed man.

"She eventually gave in, fell head over heels for him and then - yep - once he had made his conquest, he dumped her."

We reckon it's his loss!
