When I was a child I wanted to be... a taxi driver, and then I thought it might be more up my street to be a singer.
You wouldn't know it but I am very good at... directions. I can always get out of a sticky situation and find the way.
You may not know it but I'm no good at... cooking – it's something I've always wanted to learn but never been any good at. I think it's the timing that I can't seem to get my head round.
My favourite item of clothing... is my short shorts. I have a few different pairs but there are some denim Levi cut-offs by "Bitching & Junkfood" that I always wear, again and again.
It's not fashionable but I like... Seventies' tie-dye and hippy clothes. I went to see Hair, the musical, and fell in love with the fashion, even though some of it was a bit disgusting. They were all just so cool and relaxed with it, maybe it was the people I liked over the clothes!
I drive/ride... a Toyota Prius. I know they're supposed to be environmentally friendly. I'm not sure if they actually are making much of a change, but I love mine anyway. All my friends call it a spaceship. And it is cheaper to run; I hardly ever have to fill up with petrol.
My house is... actually a flat, and I'm just redecorating it now. I am thinking about putting a massive papier mâché collage of my favourite images up on one of the walls. I promise it's not so that I can play with PVA glue again like in school – I remember loving peeling it off my hands.
My favourite work of art... is a beautiful painting my best friend Jessica drew of me and her when we were 14 or 15. It's the best present I ever got.
My favourite building... is the British Telecom Tower in central London I love it so much. My granddad used to work there when it was the Post Office tower and whenever I see it I always feel homely. I saw it from the aeroplane yesterday when we were landing from Australia in London – it was nice to see it, even just for a second.
A book that changed me... The Narnia Chronicles, I've read them over and over again since I was young to keep installing imagination inside my brain. When I first read them, I remember thinking how beautiful it was that someone could create this in their mind and share it with so many people.
Movie heaven... I've just watched Band of Brothers which has haunted me and touched me so much. The portrayal of the airborne soldiers in the Second World War is as real as I can imagine.
The last album I bought/downloaded... was Cee Lo Green's The Lady Killer. I'm really enjoying it so far even though I've only listened to it a couple of times.
The person who really makes me laugh... are all my brothers and sisters. They crack me up, their sense of humour is incredible and they constantly keep all of us on our toes!
The last time I cried... was watching Band of Brothers. I think anyone would cry, no matter how macho they think they are. What's the point? The point is, there is no point, so we might as well get used to the fact that we'll never know, and live life in every moment, enjoying ourselves. There is certainly no point in harming one another in any way.
A life in brief
Eliza Doolittle was born Eliza Caird in London in 1988. The daughter of RSC director John Caird and theatre star Frances Ruffelle and the granddaughter of stage school founder Sylvia Young, Doolittle chose a career in pop instead of following her family's theatrical tradition. She broke into the singles charts in April with "Skinny Genes", which was re-released last month. Her debut album reached number three in the UK albums chart in the summer. She continues to live in her native Camden
