Katy Perry's new fragrance has been inspired by her world tour.

The 'Firework' hitmaker has been working on Meow, the follow-up to her debut perfume Purr and admitted the sweetness of the scent comes from her on stage set which resembles a giant confectionary world.

She explained: "Purr to me was a little bit more floral, and Meow is a little bit more sweet. It was probably because of the California Dreams tour that it was more of the confectionary world, because everything I've seen for the last year has been like cotton-candy scented or huge peppermints or massive gummy bears."

Katy also revealed she is a huge fan of singer and fashion designer Gwen Stefani because she admires the "quality" of the products she produces.

She told WWD: "I think she's such a great Example of a woman who puts out quality products associated with her name. That's because she's not shoving it down anyone's throats. She has great taste, great timing and she's got a cool style about her. I have seen a lot of the perfumes out there - some of my peers - and I'm like, 'Did you really approve this?' I guess I'm personally offended because maybe I do like that person's music, but you've got to make quality decisions. You can't just cash in all the time. I've always told anyone I'm working with that if I don't like the product, I'm not going to show up."
