Who to write to?

By my reckoning I am unlikely to get a response from the first "celebrity" I write to and the whole point of this challenge is to get a response.  Stage one, therefore, is to come up with a list of people to write to.  I am planning on going the whole hog and actually handwriting a proper letter.  I was also planning to write to people that I would be interested in hearing back from, i.e. people I like.

This means another list.  This is who I have so far and hopefully letters (personalised not generic) will be going out soon:

Paul O'Grady
Eddie Izzard
David Walliams
Ant and Dec
Kirsty Allsopp
Gok Wan
Jenson Button
David Tennant
Michael Buble
Richard Hammond
Davina McCall

Paul thinks I should also write to people I don't particularly like so there might be subsidiary list.
