Go backstage at The X Factor's Big Band Night rehearsals

Here's a backstage look at tonight's X Factor as contestants prepare for a night at the Proms.

Currently a total of 8 contestants are left in the competition after Giovanni Spano and duo Misunderstood were eliminated last week.

In the Girls category mentored by Simon Cowell are Bella Penfold, 19 from Essex, Scarlett Lee, 20 from Surrey and Shan Ako, 25 from Croydon.

Left in the Boys category mentored by Louis Tomlinson are Anthony Russell, 28 from Liverpool, Brendan Murray, 21 from Galway and Dalton Andre Harris, 24 from Jamaica.

The Overs category mentored by Ayda Williams are down to just Danny Tetley, 37 from Bradford.

Finally, in the Groups mentored by Robbie Williams are only duo Acacia, 15 and Aaliyah, 14 from London.

Robbie is once again away this week and so guest judge Nile Rodgers will be taking over again, mentoring his act and giving his opinions on the finalists.

You can see the full list of tonight's X Factor song choices here which include the likes of songs from Frankie Valli, Billie Holiday and Bobby Darin.

As always, the judges will offer up their opinions before the viewer poll opens to determine who stays and who goes.

Ahead of the latest live performances, bookies have installed Dalton as the 'unstoppable' favourite to win.

Aoife Heffron, Spokesperson for bookmakers BoyleSports commented: “Dalton Harris is in a league of his own and has everyone waiting for his next performance as he continues to stun with his vocals each week. It’s not surprising punters are in a frenzy to get behind him to win and he’s now odds on at 4/6 as a result of that strong support.”

It's expected another double elimination will take place on Sunday's results show, which will also see performances from Cheryl and Tom Walker.

For now, The X Factor 2018 begins Saturday at 8:10PM on ITV with all the live performances.
