When I got pregnant with my first child I gained nearly 5st. I did a bit of pretending: "I'm just really small, so I just put on a lot of weight when I'm pregnant." That is true, but I also ate a lot of cake.

I tell people that I'm a Christian, but I don't think it's giving an insight into who I am or what I'm about.

I don't get star-struck at all.

I don't leave London, really, and I don't do theatre, because I want to put the kids to bed.

TV feels quite constipated, and the thing I find particularly difficult is the branding of the channels where it's not 'Is it a good script?' but 'Is it a BBC2 script?'

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

I've got a great relationship with my dad, but I can imagine how annoying it would be if I had to move back into his house.
