I have a split personality: Katy Perry

“My sense of style is like one of those things that change colour with mood,always evolving. When I get up,I choose my outfit depending on my state of mind. If it is a ‘mixture of many things’ it is because I feel many different emotions at the same time,to the point where you feel you almost have a split personality,” she said.

The 27-year-old singer is a big fan of Madonna and she admires the way the Queen of Pop constantly reinvents herself.

“I think Madonna – especially early in her career,when she was laying the foundations of her character – has been able to evolve constantly,managing to give the audience at every appearance a new visual interpretation and concept of herself.

“I hope to do the same,to make sure that people continue to be interested in me and in 10 years,to find out that I have produced songs that will never be forgotten.”
