Katy Perry’s hair has gone “slime green for spring!”

The Roar singer is known for having dyed her hair every colour under the rainbow, and now she’s rocking the green.

29-year-old Katy showed off her latest hair transformation yesterday, posting a picture of her short hair, which she has dyed different shades of green except for the fringe.

The excited singer captioned the picture, “Slime green for spring!”

Katy has been talking about taking the ‘slime green’ plunge since last month.

She said, “I’ve wanted to go slime green for a long time. It’s spring time and I think it’s time to freshen up my look.”

“I’m really excited about slime green, but I hope my hair doesn’t fall out,” she said.
