A musical film is my idea of heaven. You can pre-record, you don't have to sing live. Singing live was the bit I hated the most. I never felt like a confident singer.

I think it must be hard being David [Tennant]. I get a certain level of attention but - I've seen it in action - he can't move for attention.

In the next few years I'd love to play a female version of Doctor Who. I know exactly how I would play her - she would be crafty in a clever kind of way.

I'm happy in the UK. I absolutely love it and I've finally got a great group of friends. I've got a lovely little flat and my work's here.

Weight doesn't matter as long as you're happy with yourself.
