I voted 8. I get better looking every year. If I were taller and bulkier, I'd put myself in for a 10. Sadly, I just have to rely on my pretty face.
Seriously, though, it's so much of "in the eye of the beholder" that it's insane. When I went to rating sites, I would often vote insanely different to most other people. For example, I find Kimberley Walsh to be far more attractive than Cheryl Cole, yet Cheryl is always the one in Girls Aloud that everyone goes on about. As for Sarah Harding, I don't even know what people see in her, she's never been attractive to me at all.
