When you think Will Young and Gareth Gates released a duet version of The Long and Winding Road you'd think that there might have been a few X Factor acts that could have released duet singles or guested on each others albums, but not so far.

I'd like to have heard a Leona Lewis and Rebecca Ferguson duet or what about One Direction and Little Mix?

I would want Alexandra & JLS to release that Bad Boys duet they did and 1D and JLS to release the She Makes Me Wanna / What Makes You Beautiful duet too.

I'd love to hear Cher Lloyd and Little Mix, Amelia and One Direction & Leona and Alexandra duets.
