My mother Diana was a true-blue aristocrat, descended from William the Conqueror and listed in 'Burke's Peerage.' My father David, from a poor Scottish family, was a doctor.

I love Monet - I've nicknamed him King Blob. When you go up to the painting, it's a series of blobs - amazing.

There are actresses who've had expensive work done and look great, so I'm not holier-than-thou about it. But it wouldn't be for me, perhaps because I've already been in hospital and wouldn't want to volunteer myself for it again.

I watch people from the top of buses who don't know they're being watched. It's quite fascinating.

I've had to spend an awful lot of my life trying to pretend I'm not posh. Although once I open my mouth, I rather let things out the bag.

I'm a bit of a fraud, really, as I didn't study acting at a drama school.
