I'll probably call her Kate Middleton all the time. ;)
It's gonna take a bit of getting used to....

Yeah I agree with xrockstarx :D

^Yerp agreed.

Catherine doesn't fit her, she's much more of a Kate.

^agree, Kate is like a friend Kathrine is so formal

kate or princess catherine. has a nice ring to it though she is not a princess

I don't think that we should call her Catherine JUST because she's now a part of the royal family. I prefer Kate anyway xx

She's not a Princess, her title is actually "Duchess of Cambridge" (:

And I'm going to call her Lady Catherine now xP Or sometimes Lady Kate :))

i like kate. its such a beautiful name haha.

I think I will always call her Kate, for me she will be always Kate. Smiley, open just beautiful person :) Catherine is too serious for me, but well it supposed to be, coz now she is a Princess ;)

I prefer Catherine, Catherine sounds more elegant and timeless.
