X Factor 2015: One Direction and Coldplay to perform during finale at London's Wembley Arena

The X Factor 2015 finale is shaping up to be a not-to-be-missed show with Coldplay and One Direction confirmed to perform during the episode. The live show, which is set to take place at London's Wembley Arena on 13 December 2015, will see the contestants whittled down to the winner of this year's singing competition.

British band Coldplay are expected to perform a track from their new album A Head Full Of Dreams while 1D will most likely sing their new single Infinity. A source told The Mirror: "Coldplay are a huge act, and this will be a key performance. There've collaborated with Beyonce, Noel Gallagher and even Chris [Martin's] ex-wife Gwyneth Paltrow appears on the album.

"Who knows who they could bring as a surprise guest? That topped with an emotional goodbye from the 1D boys as they bid farewell from the stage where they were formed will make for a great show." Following the release of their fifth studio album Made In The A.M., 1D members Harry Styles, Liam Payne, Louis Tomlinson and Niall Horan are preparing to take a break from the boy band so the X Factor performance will be one of their last.

Rumours are also circulating that Adele could join the line-up in promotion of her new album 25, which was released earlier in November 2015. The insider explained: "Adele would be a huge draw for the show and producers are desperate to snare her. She's the biggest star in the world at the moment, and they'd love her to team up with one of the girls or Che [Chesterman]. It would be a Beyonce-style moment for the contestant and would make great TV. But that's down to Adele, it's her call."

Producers are reportedly yet to confirm the three singers to perform with the final contestants but Adele has previously admitted she would be keen to take the role if the finalists were genuinely talented. The Hello singer once said in 2012: "It depends who's in it. If they're rubbish, then no I won't."

Contestants Che Chesterman, Louisa Johnson, Reggie N Bollie, 4th Impact and Lauren Murray will continue to fight for their place on The X Factor on Saturday (28 November 2015) when the show airs on ITV.
