Girl group Four Of Diamonds are favourites to exit The X Factor this weekend after two straight weeks in the bottom two.
The remaining singers will battle it out for a place in the final seven after Gifty Louise departed the competition following last week's Halloween special.
Contestants will take on girl band and boy band hits in this week's competition, reigniting classic songs from groups including Wham! and The Beatles.
The bookies' favourite remains Matt Terry, who will sing Wham!'s I'm Your Man, although Emily Middlemas, who collapsed into tears at the end of her rendition of Radiohead's Creep during last Saturday's show, has had her odds of winning the show cut from 14-1 to 3-1.
Emily will take on former X Factor stars One Direction's What Makes You Beautiful.
Controversial act Honey G will sing American hip hop duo Kriss Kross's hit 90s track Jump, days after Lily Allen described her as "offensive" and "so wrong on so many levels".
As well as Four Of Diamonds, the favourites to leave are Finnish singer Saara Aalto and Ryan Lawrie - who will be twisting and shouting to stay in the competition as he performs The Beatles' classic hit.
"Four Of Diamonds have been in the sing-off in each of the last two weeks, however, we think their luck is about to run out as we make them favourites to depart this weekend," said Coral's John Hill.
The group will sing Hold On by American group Wilson Phillips - while Sharon Osbourne's act Aalto will perform Sound Of The Underground by Girls Aloud.
:: The X Factor returns on Saturday night at 8pm.
