Im a size 12 and Im very happy with it.

I'm a mother of three children, and we do make mistakes.

I prefer watching movies on the sofa rather than sitting next to Bob Geldof at a premiere and wanting to kill yourself.

There's nowhere to hide in the theatre. You can't be the one in rehearsal who doesn't know their lines.

I am delighted to join Doctor Who and to be working with this incredible team. Ms Delphox is a great character and someone I've had a lot of fun playing.

I think if you do a lot of interviews, you're laying yourself open. If you put yourself out, accept every invitation to every premiere, then you can't really complain when people knock on your front door and photograph you in the street.

I've never seen an episode of Downton Abbey.
