Aww, why so grumpy, Katy Perry?

The newly-divorced singer was photographed leaving the Miu Miu fashion show in Paris today, and while there's nothing wrong with her colorful outfit, her Smurf-hued ponytail is a big blue miss. We know she's no stranger to switching up her hair color, but this dye job is fading faster than Russell Brand's interest in his latest yoga classmate. And those roots? Yikes!

We love Katy, but we think she needs to book an appointment with her colorist ASAP! Hmm, what shade do you think the "Firework" singer should dye her hair next?
