Katy Perry models herself on Freddie Mercury.

The 'Roar' singer takes not just her musical stylings from the late Queen frontman, but believes he helped make her a confident woman.

She told the UK edition of Cosmopolitan magazine: ''Queen's track 'Killer Queen' made me discover music and helped me come into my own at the age of 15.

''The way Freddie Mercury delivered his lyrics just made me feel like a confident woman; I'd say his fingerprint is all over me in general. And I also love the idea of a woman who reigns and has power, like Queen Elizabeth in the UK.''

Katy, 28, also said she loves experimenting with her look, and doesn't worry if she's not always perfectly turned out as it shows her humanity.

She added: ''I love having fun with my looks. I want to present myself as a human being, with lots of different aspects that aren't necessarily perfect.

''I think it's totally fine to accept everything you have if you can. It's good to try and have a certain grace with everything, but a sense of humour is most important. I try not to take myself too seriously.''
