But Katy has also attracted a fair amount of debate thanks to I Kissed a Girl and another song, UR So Gay, which attacks a straight man and explains that his problem is that he has too much in common with gay men (for this to work you have to share Perry's world view that gay men are all exactly the same). Perry's a fascinating modern pop artist and the mechanics of her launch - on both sides of the Atlantic - have been clever and, despite the heavy handed sloganeering of her debut hit, quite subtle. Good lord, this is racy stuff which will totally unintentionally steam up the glasses of Daily Mail readers at breakfast tables across the land. 'The taste of her cherry chap stick, I kissed a girl just to try it, I hope my boyfriend don't mind it, it felt so wrong, it felt so right.' 'I kissed a girl and I liked it,' Perry declares. Part of the reason it's heading to the chart pinnacle is that it's quite good, and part of the reason is that it agrees with the Zoo, Nuts and Babestation belief that women, whether straight or gay, all actually like lezzing off with each other.
