Do we know who either of the guests are this Sunday yet? Or for any future Sundays?

Not sure who's around at the moment who they'll have on. The guests last year were really weak though (except the final) so hopefully this year is an improvement.

Previous X Factor acts - expect Little Mix, Olly Murs, Fleur East, James Arthur, Louisa Johnson, alongside the likes of Ariana Grande, Zara Larsson, Shawn Mendes, Fifth Harmony.

In terms of bigger acts, maybe Lady Gaga or Britney Spears.

All will inevitably be forced to say they're loving the show as they scramble around to think of the name of one of the acts they're "rooting for".

I guess the likes of LM and 5th Harmony will be churned out.

It's pretty obvious they'll want 5H and LM to perform since they're the main success stories right now, alongside Olly. Might as well remind the public that sometimes they can produce great pop acts.

it's apparently james Arthur and someone else

Fleur little mix fifth harmony Louisa will be in coming weeks i imagine!

Fleur East, James Arthur and Fleur East

lol, and it'll be Sax twice

I really don't want to see James Arther on my tv thank you.

nah she isnt on the show this weekend, shes finishing off her second album

Micheal buble and Robbie Williams will be on soon ,100% sure

Leona could make an appearance too.

Bruno mars maybe new material is out

me neither ha, don't know why you chose me to quote when I never mentioned this dork

Agreed.

Very predictable bookings, along with Leona, Olly Murs and Little Mix.

Lady Gaga and One Republic might feature, too.

Has Meghan Trainwreck (sorry, Trainor) got anything new coming out? If so add her to the list of maybes.

Britney is in the uk

Louisa will be back at some point

James is performing on the Sunday

Also the contestants are performing their group song which is SAX by Fleur on Sunday too

Both have new albums out soon so it's a good bet.

Who told you that shraine haha I always wanted to hear Gifty singing sax so yah!!

I think James Arthur and Robbie will perform this weekend.

Others that will probably perform: Little Mix, Fifth Harmony, Olly, Louisa, Ellie Goulding, Lady GaGa, possibly Rihanna and Drake (I think Nicole is friends with them). Then I'm sure we will have the slightly boring people e.g. Buble and Mary J Blige.

I'm most interested to see if they get Zayn and/or Niall to perform. Simon doesn't seem to be on good terms with them?

Can they both be on Big Band Week??

Reggie & Bolly ????

Mostly shite then.

Spice Girls GEM perhaps? He did have 2 of them at Judges Houses.
