Kesha has ditched the rainbow hair, gone back blonde and embraced a full-on Barbie girl look in the latest of her Instagram uploads.

“Dead about the head to toe miu miu today so many colors!!” wrote the ‘Timber’ singer, alongside a photo of her hopping out of a car in a pale pink knit and Schiaparelli shorts, teamed with cat-eye sunglasses.

“Back to blonde but got rainbows in my heart,” Kesha added on a selfie, focusing in on her Miu Miu shades and Malibu blonde hair.

Having previously dyed her famous mane pink, captioning that photo “save the boobies! #pathwaytothecure,” we can only assume that Kesha’s all-pink outfit is her way of preparing for Breast Cancer Awareness Month this October. Or preparing for Wednesday, because on Wednesdays, we wear pink.

With all this bubblegum around for autumn, and into Spring/Summer 2014 thanks to Jeremy Scott’s Barbie-themed Moschino show, just how should we mere mortals tap into the trend?
