There are those who say that brand partnerships is the way forward for musicians. Not Katy Perry though, who has hit out at fellow pop stars who flog stuff to make a fast buck instead of trying to make better music.
She told The Daily Star: "I work every day and nothing is for free. I'm not some fucking idiot wasted pop starlet lost on an island somewhere. I have a job, I know my responsibility and I'm always trying to take it to the next level. People had a bet on my head that I'd have to dip out because I wouldn't be able to handle all of it. I went and played every show, then I sold out a 50-city, around-the-world tour, which is awesome - and most of these bitches just hawk breath mints or shoes. No offence to them, but maybe I'll hawk shoes later in life".
