The singer, 26, showed off her dramatic hair change during a promotional appearance for her first fragrance, "Purr" in Canada on Thursday where she posed on the purple carpet in a demure lilac knit cardigan and skirt by Dior, paired with purple Miu Miu peep-toe pumps and yes, cat ears.
Earlier this month she hinted via Twitter about switching up her hair color: "Tonight I dye my hair a different color. Can you guess which color?" she asked her followers June 16.
The next day, the pop star tweeted, "So I didn't get to the exact color I wanted from being black for so long! To get to goal I have to be a ginger for three weeks!"
Still no word on what Perry's "secret color" is, but we'd loe to see her go blonde for the summer.
