Singer Katy Perry has labelled her debut fragrance, Purr, the 'Goldilocks' of perfume. 

The 'Teenage Dream' singer gave an interview to Entertainment Tonight Canada, where the scent is currently a best seller, and explained that "it's basically me in a bottle":

"It's like the Goldilocks of perfume. It's not too much, it's not too forgettable, it's just right. It's basically me in a bottle. I think a lot of people go up and they go, 'That's definitely Katy Perry. This is definitely Katy Perry's perfume.'"

She also added that she likes to glam up spritzing on the perfume by walking through a mist of it:

"I've heard that you're not supposed to spray directly on the skin. Then it's not so concentrated, because everybody knows sometimes when a woman walks into a room, she can smell like her grandmother."
