With two contestants already gone, the remaining X Factor finalists will be pulling out all the stops to impress the judges and viewers on Saturday night.

The theme this week is ‘Big Bands’ and all the acts are said to be working extra hard on their performances for Saturday’s live show.

With all of her three acts still in the competition, the pressure is on judge Dannii Minogue and the boys to secure another clean sweep.

Heat magazine’s ‘Torso Of The Week’ Andy Williams will be singing This Guy’s In Love while Leon Jackson is looking to up his game with Fly Me To The Moon.

Resident showman Rhydian Roberts will be tackling Pink’s Get The Party Started.

With Kimberley gone and Alisha in the bottom two again last Saturday, Sharon is desperate for her girls to do well on Saturday night.

Alisha Bennett will be singing The Zutons’ hit Valerie while 15-year-old Emily Nakanda will be performing Bjork’s It’s All So Quiet.

Following Daniel’s departure last Saturday, it’s up to the two remaining females in Louis’ Over 25s to steal the show.

After her spell-binding ballad last week, Niki Evans will be turning up the tempo with All That Jazz, from the musical Chicago, while teacher Beverley Trotman will be performing Feelin’ Good.

And Simon is hoping to retain all of his groups for a third week running.

Boy band Futureproof will be performing Can’t Take My Eyes Off You while girl group Hope will prove they’re naughty but nice once again with Madonna’s Hanky Panky.

Brother-sister duo Same Difference will be embracing their ‘cheese-tastic’ image singing S Club’s hit Reach.

The results show features a special performance from US R&B stars Boyz II Men.
