Katy Perry has gone green!
The singer debuted her brand new look on Instagram last night, posting a pic of her freshly dyed tresses. "SLIME GREEN FOR SPRING," she captioned the image, after getting her hair did at The Chris McMillan Salon.
It's definitely a different look for Katy, who has been rocking a black bob with blunt bangs recently -- but she's also no stranger to brightly colored locks.
In the past she's sported a variety of candy-colored wigs and has also dyed her mane blue, purple and pink.
