Ke$ha puts a sexy twist on the actually-I-wouldn't-get-too-close-I'm-not-sure-where-she's-been look.
She once defaced the Hollywood sign, except she actually didn't, it was all PR LOLZ.
Her songs are often very catchy indeed. It is impossible to not dance when listening to 'Take It Off'.
Ke$ha took LMFAO on tour with her, which will probably be regarded as a criminal offence in a few years' time, a bit like when people decided that elephant tusks were generally not the sort of thing you should make stuff out of and everyone had to get rid of their ivory kettles.
She co-wrote Britney's 'Till The World Ends' and appeared on a remix that also included Nicki Minaj.
Well done Ke$ha.
In 2012 she claimed to have invented a new musical genre called 'cock pop' and admitted to having sex with a ghost.
That same year she released her second album 'Warrior', which charted in the UK at Number 60.
