Doctor RooVery Happy Birthday to Katy Manning.
I think... no, actually, there's no need to think about it - Katy Manning IS my favourite celebrity from Doctor Who that I have had the pleasure to meet in person. Actually, no, I'd go further than that - Katy Manning is my favourite celebrity from ANY TV show or movie that I've had the pleasure to meet in person. She is just so nice and so wonderfully bonkers, I'm smiling now just thinking about the time I met her. Wonderful lady.
