Wasn't she going to help out in someway? She was on the first show, I think, interviewed whilst sitting in the audience, but I've not heard anything since.

She is going to be a judge for the final stages of the competition,1/4 final onwards I think.
She lives in Australia so that is probably why she hasn't been around for a few weeks.

I think she'll be in the audience next week seeing as they are going to Blackpool.

But the quarter finals is when she starts off judging, through to the final.

I wonder if she'll stay for the Christmas Special? I know that doesn't matter as much as the main series, but due to there being 4 39s last year she might help get rid of such ties.

More like shes seen whats gone before and thought 'nah, dont fink Ill bovver fanks!'

She was asked to be a Judge, her Husband was not keen on her being in the UK for that length of time. They have two young daughters so, she will be there nearer the end.

It's just another stunt by the BBC to get a "name" in the credits.
I can't see what she can add to the judging of ballroom dancing, but then I can't see what Alesha does either.
