Hi, It was known over here ages ago.
The big controversy is the new doctor is a guy called Matt Smith and he's very wierd looking!!

I love David Tennant. I think the problem is that people take the job on, but then they don't want to be typecast as doctor who forever, so they move on.
The worrying thing is, the doctor is only supposed to have 13 incarnations before he dies, Matt smith will be 11th (not counting a mad Children on Need special when they got through about 5 incarnatiosn in 20 mins!!) So they are running out.
I'll be sad to see Tennant go - but then I was discussing with work collegaues that I would like a really young doctor (he's my age!) to see a Young man trying to play an old man in a young man's body. Still, I trust Steven Moffat.
That, and I prefer Torchwood anyway!
Here's my boyfriend as Captain Jack Harkness-
I love cardiff.
