Rachel Hylton is the favourite to be voted off The X Factor on Saturday night after twice ending up in the bottom two.

Bookies are giving odds of 5/6 for the troubled single mum to be eliminated from the ITV1 show, with Spanish singer Ruth Lorenzo next at 15/8.

Rachel, who has made no secret of her criminal past, was criticised this week for making was appeared to be a gun gesture on last Saturday’s show.

But during her Take That masterclass this week she was advised by the group’s Mark Owen to forget everything else and enjoy the show.

Finalist Alexandra Burke, however, may struggle to enjoy Saturday night’s show – she will be battling a sore throat as she sings the band’s hit, Relight My Fire.

Meanwhile, it’s been reported that Diana Vickers, who missed the live show two weeks ago with laryngitis, is apparently dating fellow contestant Eoghan Quigg.

According to The Sun, the pair – who have claimed they are ‘best friends’ – were spotted canoodling by the show’s researchers in the house the finalists share in North London.

A show source said: “They’re only young and hormones are flying about the place.

“They’ve got a really sweet relationship — but we did have to avert our eyes.”
