Rihanna goes gray, debuts new hair color on Instagram

Who are you calling granny?

Rihanna is no stranger to changing her look -- the stylish Barbadian has gone from bright red pixie cuts to bleach-blonde waves and back again. But on Wednesday, the 25-year-old singer took to social media to debut a hair color that isn't exactly representative of her age.

"New color ice grey ish, call it #Brrr," the 25-year-old singer wrote alongside an Instagram photo of herself sporting long black hair with prominent gray streaks.

"Grey is the new black! Blondies, it's quiet for y'all! #brrr" she declared in a later post.
