I worked in Bhs, but I was only there for a couple of weeks before I got fired because I needed the Saturday off to go to drama club. I was useless - I was so bored. There was nothing to do, so I'd go and do a circuit of the store, throwing jumpers on the floor, then go and pick them up. It wasn't rock 'n' roll rebellion, it was just to look busy. They tried to teach me how to work the till and I'm useless with numbers, so I was making it all up as I went along. I must have lost them tons of money.

I have to keep Dune perfume in my dressing room, because I always wear it, but I must never put it on in case it makes me choke.

And people are so het up about the fact I'm in the theatre - it's like, 'Ooh these telly names, can they be any good?' I came out of RADA and my first job was at the National Theatre, but everyone wonders if I can cope. It makes me laugh.

I was always the one in the background or the donkey. I was never a star, I never got to be the main part.

As soon as you meet him [james Corden], within five minutes you'll want to sleep with him. He presented me with my award for Comedy Actress of the Year at the Glamour Awards and he said such lovely things. He's so charming and he listens to you and he's funny and sensitive and adorable. I can totally see why all the women fall for him.

He's always been absolutely gorgeous and had that charm, but he was in a steady relationship until quite recently, so it's only of late that all the girls are like, 'Oh my God, oh my God'.

My husband would say my signature dish is pasta with a tin of tuna plonked on top. So, no. Although I make a good bangers and mash. I have been known to stick cocktail umbrellas in it, take a photo and send it to James upstairs with a text saying, 'Your food's ready'.
