I truly would love to be a designer-label girl, but I am very much High Street.

When I write, I create really absurd situations which become false because I am after the joke.

I once had a friend who did the hair for sci-fi movies, and after a particularly bad break-up I stupidly went to her salon and told her she could do anything she liked. She dyed the bottom cherry red and the top peroxide blonde.

I have three boys, so I live in a household full of testosterone.

All I want to do really is get married and be a matriarch.

What having a Down's syndrome child isn't - and I feel very strongly about this - is a tragedy. All those pregnancy books you read when you are expecting refer to Down's syndrome as if it were the worst possible outcome, and it's not.

As a writer myself, my job has very often been to also write on the job. So you get the script and a vague idea of how the scene might work, and you then add funny words or change the script. I'm not the world's best writer or the world's best actor, but I can do that thing where I can fix - or ruin - fix-slash-ruin, add quirk, add value.
