When I was 12, I had an operation at the Royal National Orthopaedic Hospital, and they corrected the curving in my spine. I've got two 12-inch rods and eight screws going up my back keeping me straight, and they fuse together with my spine, so now I can't really live without them.

Beatrice loves her glamorous dresses and her hair being curly or big - like Mummy's - and I hate volume. I like my hair to be sort of flat. I like just throwing on a pair of jeans and generally being more understated. She is more 'Let's do the glamour.' We're chalk and cheese.

I am definitely not as polite as Beatrice, I have to say. I tell it as it is. I am shyer at first.

I so want to be able to speak another language. I love the way my friends who are half Italian and half English break from one language into another without even pausing.
