Pic: Who is the mystery Corrie Christmas bride?

Coronation Street publicity manager Alison Sinclair tweeted a teaser of a picture today. 

Alison is on twitter at @aliJcorrie and said this today in a tweet as Corrie gears up for Christmas: "A touch of the Wizard of Oz comes to a little wedding tease"

So, who do you think the mystery Coronation Street Christmas bride will be?  We know there will be a Corrie wedding this Christmas as producer Phil Collinson has already told us one will take place.

Let's think who it could be:
Carla and Peter - but would Carla wear red shoes? I'm thinking not.
Leanne and Nick - it's possible, yes.
Julie and Brian - my favourite leading guess. With her retro fashion sense, ruby slippers would be right up Julie's street. 

Who do you think it could be?
