Also, I think women really come into their own in their 30s.

Now when I say Sophie Ellis-Bextor I feel that's not really me because that's become this entity from doing the gigs and the shows and the make-up contracts and whatever else.

Getting up to dance to your own stuff looks pretty pretentious. And leaving the dancefloor when it comes on is just awkward.

Some people can get away with being very sexy to men and not looking like a complete cow, but I didn't think I was in a position where people knew me well enough

There are a lot of people out there who lie about their age and I think it does us all a disservice. It can't all be over when you hit 30. That would be rubbish.

I'm always sticking up for other people.

In real life, I'm not super-posh but if that's the stereotype, I really don't care. It could be worse.
