Katy Perry is "turned on" by women.

The 'I Kissed a Girl' singer insists she is not a lesbian, but enjoys "chatting up" attractive women, like British supermodel Agyness Deyn.

The 24-year-old star said: "I have talked a lot about wanting to kiss girls, but am I a lesbian? No. It's just a kiss. I would like to get it on with Agyness Deyn.

"She's a little punk-rock Lolita. Beautiful face, beautiful shoulders. I look at her and I think, 'Ooh, I'm so turned on. What's happening?' "

But when Agyness is not around, Katy goes to gay clubs to flirt with lesbians.

She explained: "I get hit on when I go to gay clubs, but I hit on women too. Beautiful ones. I'm attracted to cool, alternative women. But I'd only ever have a drink with them. I'm such a tease!"

Katy insists it's normal for teenage girls to indulge in homosexual trysts.

She told Britain's The Sunday Times newspaper: "It's a girl thing. If you sat a group of teenage girls down and asked them, they would be like, 'Yeah, duh, I've kissed my best friend before. What's the big deal?' "
