Katy Perry would quite like her career to emulate Madonna's if at all possible thanks.
At pains to point out that it's the beginning bit of Madonna's career she'd like to replicate, the 'If You Can Afford Me' chanteuse told L'Uomo Vogue (as quoted here): "I think Madonna, especially in the beginning of her career when she was laying the foundation, was evolving every single time and giving a new visual and a new idea to the public."
"She kept everybody interested because you never knew what she was going to do next, but whatever she delivered was a solid product," she continued. "I just hope to be the same. I hope to continually make people interested and hopefully in 10 years look back and have written songs that have become timeless."
She also said that her next album will be "much darker" than 'Teenage Dream' and that we'll "discover another part" of her, which is good to know.
