The X Factor has unveiled new portraits of the final 12 contestants ahead of the live shows this weekend after the hopefuls got their superstar makeovers.

Wicklow brothers Sean and Conor Price impressed Simon Cowell in the Judges' Houses episode, with their cover of Pink's What About Us, and the sibling duo are set to tackle London Grammar's Strong during Saturday's live show.

The Blessington boys looked slick in a varsity style jacket and logo-shirt along with ripped jeans. Sharp!

Fellow sibling group The Cutkelvins will be singing Pink's What About Us on Saturday. The Scottish trio went for an urban look in their photoshoot.

Watford band Rak-Su, who will be performing Mamacita for the live show, went for tonal black and white sweaters with touches of red for their photoshoot.

15-year-old Holly Tandy from Barnsley, who was only able to appear after the age limit for this year's series was lowered, stunned in a tailored navy and white pinstripe crop top with matching high-waisted trousers.

Grace Davies, who is also one of Sharon Osbourne's Girls, went for a fashion forward look of a choker necklace with a shirt dress worn casually off the shoulder.

Mum of three Tracey Leanne Jefford, who is part of Nicole Scherzinger's Overs group, had a particularly dramatic transformation, wearing a beautifully fitted white suit along with sleek locks and subtle smokey eyemakeup.

Sam Black, one of Louis Walsh's Boys, showed off his tattoos in a crisp white crew-neck tee paired with perfectly tailored grey slacks, wearing his hair suitably coiffed.

Spencer Sutherland had more of a rocker vibe with expertly mussed up hair, a cosy jacket and hoodie and ripped-knee jeans.

Essex singer Matt Linnen, 28, looked striking in an utterly pared-back look - a grey marl crew neck tee and black jeans.

This year's live shows will be different to previous series of The X Factor as there will be eliminations on both Saturday and Sunday.

As well as that, the judges will be powerless to save their favourites as the sing-offs have been scrapped for the bottom two of the public vote. Instead, the act with the lowest votes will automatically exit the show.

The X Factor judging panel, Nicole Scherzinger, Sharon Osbourne, Louis Walsh and Simon Cowell, and host Dermot O'Leary also got treated to a glamorous photoshoot ahead of this weekend's live shows.
