Some of you may know, it's Rhianna & Rebecca ferguson next week along with the acts below in forthcoming weeks.

Leona lewis, Joe mcelderry, olly murs & even Tulisa, Kelly & Gary!!!

Is Leona a guess? Because we're not sure she's going to be on any more this year, seeming as her album has been pushed back until March, plus there is no sign of a single.

She said she confirmed it in september. But that could change.

Oh ok

I reckon she could be asked to do a duet with a finalist perhaps....

Leona Lewis was going to perform but she isn't releasing another single until around her album release (March 2012) so I imagine that's cancelled now and she didn't know when she confirmed her performance.

wow, rihanna apart, what a load of crap.

This is the schedule so far. Rebecca was due to perform next week, but now it's the week after I think.

Sunday 13th November - Lady Gaga and One Direction
Sunday 20th November - Rihanna and Rebecca Ferguson
Sunday 27th November - Olly Murs and ?

That's all so far. Joe McElderry was dropped by Simon. Would be good if he did perform, but I doubt it. Leona isn't releasing anything until next year. Alexandra is sending her single to radio next month, but it's not released until January. Think that rules those three out.

Well Leona would have been on the 27th November slot, but as it looks like she's got nothing to promote, I wonder who will be given the slot. Unless Leona's still going to be on and be giving us a premiere of what's to expect next year, but it's very unlikely...

It should be pretty easy for us to work out who will be on. Does anyone know where there's a list of single and album release dates?

isnt fireflies out next month?? i thought its a late november/early december thing??? maybe she'll be performing at the semi final?its exposure she needs.

Can't wait to see Olly perform his new song - it's very catchy.

27th will be finalists song won't it? Unless that takes place instead of the normal group song?

I'm assuming it will be Kelly Rowland and Olly Murs? Her albums out the day after I think.

Is it not the charity single on the 20th November or has that been changed?

Umm Jedward and maybe Plan B, he has a new single out soon

I predict that Jessie J Adele and Maybe Nicki Minaj might be making apparances soon

I doubt Adele will as she's just had surgery on her throat and I don't think she can sing until sometime next year. It all depends on who has a single/album to promote in the next few weeks.

Kelly has an album coming out in a couple weeks time so I think she will be performing in the next few weeks. If she doesn't, I'd be very surprised.

I hear Missy Elliot and Nicky Minaj is going to appear on the xfactor along with salt & peppa

James Michael has said they're all performing the charity single next week. Kelly has also pretty much confirmed she'll be perforiming. So it's looking pretty much like this:

Sunday 13th November - Lady Gaga and One Direction
Sunday 20th November - XF Charity Single, Rihanna and Rebecca Ferguson
Sunday 27th November - Kelly Rowland and Olly Murs

I know this aint true but I would love it if it was ture !

surprised westlife wont be on for the last time

There was an entry on Wikipedia that Fireflies would be released on 27 November but there has been no confirmation from a reliable source.
