It would be funny if Louis Tomlinson turned up to sing with Matt. Louis has such a weak, spindly voice - he'd make Matt sound amazing in comparison.

Liam Payne has a similar type of voice to Matt, with a falsetto, but since he signed to UMG it's unlikely he'll be doing anything with Simon any time soon.

I'm thinking maybe Conchita Wurst for Saara.....that would be simply epic!

I'm hoping 5AM do The Hills with The Weeknd - it would be tough coz most of it would be censored but it's an absolutely sick tune and by far the best The Weeknd have.

I know the Weeknd is huge right now but can he just be guest. A duet will just be awkward since he's not a real performer! I'd rather them duet with Little Mix and have a huge performance and production

James Arthur has confirmed that he won't be singing with Matt. The rumour is false. Does that mean Nicole then?

I want Matt to sing with Nicole and do All I Ask like he did with Natalie Weiss earlier this year https://m.youtube.com/?reload=14&rdm...?v=_iztQ5TSPy8

Yes! Me too! I've been waiting for him to perform All I Ask. The duet would be amazing.

Me too since the live shows I have wanted him to sing All I Ask hope he sings it in the final either on his own or as a duet.
