Ke$ha's goal with her music is to end sexism in pop.

The 25-year-old singer found worldwide fame with her single 'Tik Tok' - which was criticised for promoting drinking and promiscuity - and she doesn't think it's fair that men are allowed to sing about getting drunk and women aren't.

She said: ''If men can talk about drinking in every awesome rock 'n' roll song and every awesome rap song, why can't a woman? Just because I drink doesn't mean I'm a drunk. Just because I have sex, and I'm not embarrassed doesn't mean I'm a whore.

''If men can do it, why can't a woman do it? I really feel one of my main reasons for being on this earth is to level out the playing field just a little bit.''

The 'Die Young' hitmaker - who is just about to release her second album 'Warrior' - considers herself a feminist and insists she is determined to push the boundaries of what women can do.

When asked if she's a feminist, she told the Financial Times Weekend magazine: ''In some ways. In the ways that I feel I can do the same things men can do, and be just as rock 'n' roll and bad ass and not feel shameful or be shamed for it.''
