Mason Noise

Mason, 22, hails from Birmingham, and was a part-time waiter before he got involved with The X Factor. He almost didn't get this far into the competition after a rant on stage during the six-chair challenge led to him being asked to leave the show by Cowell. However, after being invited back, Mason is preparing to sing Justin Bieber's Sorry.

Ché Chesterman

Like Louisa, Ché is also from Essex and used to work at Waitrose supermarket in Langdon, east London. He will be performing the mash-up of Tears Dry On Their Own and Ain't No Mountain High Enough by Marvin Gaye and Tammi Tarrell and of course, Amy Winehouse.

Anton Stephans

Anton has spent all of his life performing as a backing singer but figured he'd had enough of sharing the spotlight and decided to try and make it as a solo artist. The 45-year-old lives in London and Luther Vandross's Dance With My Father is his song of choice.

Max Stone

Max, 27, has been a bit of an underdog in the competition so far, with even mentor Cowell unsure of his stage presence and charisma despite his great voice. But after hearing how much the general public were behind him, Cowell caved and gave him a chance. He will be performing Someone Like You by Adele.
