Katy Perry has opened up on her beauty regime, admitting that she is far from low maintenance.

The Firework singer, who is launching her new fragrance Killer Queen in August, confessed that her make-up application takes up a huge chunk of her morning.

She told WWD: “I’m a product whore. I have a [beauty] regimen that spans an hour and a half, and nothing goes out of order.”

The popstar also added that her beauty regime can be challenging "if you're sleeping over at a new boyfriend's house!"

Perry also spoke about the possibility of launching fashion and beauty product, saying she would like to, but "this circus act can only juggle so many balls. I wouldn’t say never on anything, but my heart isn’t drawn to that area just yet.”
