Katy Perry makes good on her promise to dye her hair “slime green”

After her breakup with John Mayer, Katy Perry vowed to go slime green and now she’s making good on that promise. “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,” Perry told E! News last month. The pop singer has rocked every bright color of hair imaginable, so it’s no surprise she would go green. We were maybe expecting a brighter green, though.

Katy has also released a new cover for her single “Birthday” featuring her and her older sister Angela when they were kids.
