The three remaining contestants taking part in this year's X Factor are undoubtedly gearing up to take part in the live final on 12 December and with everything at stake, they will have to bring all they have got for the last performances of the 2015 series.
Ahead of the final, IBTimes UK takes a look at each contestant and their beginnings in the reality singing competition as well as what they each have planned for the upcoming live shows...
When 17-year-old Johnson from Essex stepped out on to that big stage during the first week that the auditions were on television, no one expected the powerful voice that came out of her, least of all judges Rita Ora, Nick Grimshaw, Cheryl Fernandez-Versini and Simon Cowell. Her rendition of Michael Jackson's Who's Loving You easily earned her four yes's and made her one to beat throughout bootcamp and judge's houses.
Ora's last girl standing, Johnson will taking on Christina Aguilera's Fighter as well as I Believe I Can Fly by R Kelly. She stands in very good stead of winning the competition given her track record of wowing the judges and delivering effortless performances but can she maintain her perfect streak when it matters most?
Former Tesco employee Chesterman (also from Essex), and was undoubtedly one of the standout acts throughout the audition process, impressing the judges with his flawless rendition of Jessie J's Who You Are. The 19-year-old has certainly taken on some brave song choices across the live shows, including huge classics You Can't Hurry Love by The Supremes, When A Man Loves A Woman by Percy Sledge and It's a Man's Man's Man's World by James Brown.
Throughout the final, Grimshaw's contestant Chesterman will perform In The Air Tonight by Phil Collins, and Mark Ronson and Amy Winehouse's Valerie. He's had a bit of a bumpy road recently, what with being in the sing-off last week and forgetting his lines the week before, so Chesterman has really got to pull every trick he's got out of the bag to convince the judges he should win this time round.
Reggie 'N' Bollie
No one would have guessed when likeable duo Reggie 'N' Bollie (then called Menn On Poinnt) turned up at Wembley Arena to audition with their original song, Turn It Up, that they would make it all the way to the final. They did not even get shown at Bootcamp and the duo from Farnborough certainly have not been the best singers in the competition, particularly given the exceptional level of talent this year, but it was their fun productions and energetic individuality during the live shows that kept people voting.
Unsurprisingly, one of Reggie 'N' Bollie's song choices for tonight is a mash up; Spice Up Your Life by the Spice Girls, mixed with Boom Boom Boom by the Outhere Brothers. They will also be singing 1990s cult hit, Kriss Kross's Jump.
According to William Hill, Johnson is the favourite to win for the seventh week running with odds of 1/5 and double act Reggie 'N' Bollie are in the runner-up spot with 9/2. Ché Chesterman is distant third with odds that stand at 14/1.
Tune into The X Factor Final on ITV from 8pm on 12 December with the finalists performing their two songs, including a duet with a famous singer, before one act is evicted. The winner and runner-up from 2014, Ben Haenow and Fleur East respectively, are thought to be performing as are former contestants Leona Lewis and Little Mix. Could they be the stars singing with the acts? Only time will tell...
The results show will be on at the same time on 13 December, and will see Johnson, Chesterman or Reggie 'N' Bollie perform not only their song of the series but the winner's song too. Huge acts Adele, Coldplay and One Direction are also confirmed to be taking to the stage.
