That's disgusting. I don't do that".The 'Stupid Girls' singer - who is currently involved in a war of words with hotel heiress Pairs Hilton after she included a spoof portrayal of the blonde's notorious sex tape in her latest music video - went onto admit that although she is more than happy with her husband's sexual prowess she doesn't do much work in the bedroom.She added: "I'm too lazy to go on top."Despite Pink's lack of enthusiasm, she insists she prefers men after an experience with another girl put her off women for good.She said: "I did kiss a girl it was nice, but she left me for my brother, which is pretty sick, don't you think. It was probably her who put me off women.

"I don't think I have sexual feelings towards woman. And, anyway, I like Carey's thing too much, so that pretty much rules out the whole lesbian thing, doesn't it?"
