It's another day, another ‘do for besties Katy Perry and Rihanna

They’re almost as famous for their changing locks as they are for their songs and love lives, and now there’s yet another chapter in Rihanna and Katy Perry’s hair history.

Katy, who’s been rocking varying shades of blue for a few months now, teased her Twitter followers before unveiling her latest look to the public – long deep purple waves. ”I found time to change my hair colour... Finally... #takeaguess #foreverawalkingpantonepalette,”  she wrote.

Her BFF RiRi also overhauled her ‘do, showing off a newly-darkened hue via an Instagram pic. We can’t wait to see what colour the ladies choose next – green, pink, maybe even orange?!
