Kesha is no stranger to changing up her look, but we didn't see this one coming!
The singer traded in her natural blonde tresses for a neon green hue just in time for summer, debuting her bold new 'do on Instagram.
"Slimey," she captioned the pic of her bright green locks.
Her slimy shade totally took us back to the '90s -- or is she just trying to tell us that she wants to be slimed by the lime green Nickelodeon goop?
Crazy hair color is nothing new for the 28-year-old pop star -- she has rocked just about every color of the rainbow over the years. Plus, who can forget her insane faux-hawk ... (we would like to).
We prefer Kesha as a blonde, but we want to hear from you. What do you think of her new 'do? Cast your vote above!
