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.

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

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'.

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 couldn't give a sh*t what they have to say. As soon as I go home and see my husband James Thornton of Holby Blue fame and pick up my dog and cuddle him, that's all that matters. I couldn't care if some theatre reviewer thinks my American accent sounds a bit Welsh.

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.
