I used to be absolutely addicted to the gym and I do still love it.

I'm one of these people that if I have a nice holiday - like I have had in Turkey repeatedly - I go back a lot.

I only unwind at facials and massages.

David Tennant is a massive fan, and grew up dreaming he would be the Doctor Who one day. So I did feel, when I first got the job, "Right, now I've got to do loads of research into absolutely everything Doctor Who." But that's not possible to do in a short space of time. So my knowledge has been growing and developing as I've been doing it, and that's been fine. That's been appreciated by the fans, and the executives never expect me to be brushed up on absolutely everything.

I appreciate individualism.

I'm terrified of bugs and I travel with sprays, lotions, potions; the lot. I have to check the room before I go to sleep and if I come across a bug and fail to remove it I have to sleep in a separate room as I'm paranoid that I'll be taken advantage of as I sleep.

I've had journalists beg me to please say something negative about my estate.
