Katy Perry dyes her hair “slime green” for spring!

Sound the celebrity with a new hair do klaxon*! Katy Perry has changed her hair look and it’s quite a radical new colour choice.

Katy has swapped the sleek jet black for a messy and very punk slime green – and we’re saying slime green not because we’re horrible, but that’s how Katy herself described the colour.

She captioned this Instagram pic, “SLIME GREEN FOR SPRING by my bb's @neeenaboo & @brantmayfield at the @mcmillansalon”

Is this the first time ever that a person has been influenced by gunge at the Nickleodeon Kids’ Choice awards? We’re going to say yes.

What do you think of Katy’s new green locks?
