EXCLUSIVE
X Factor favourite Diana Vickers has lost her voice and may have to pull out of tomorrow's live show.
Diana, 17, has already missed rehearsals after being struck down with a bad throat infection.
A source said there's a "90 per cent" chance she won't recover in time.
It will be the first time a contestant has missed a show in its history.
The source said: "Diana lost her voice on Tuesday and couldn't sing a note.
"She's dosed up on medication and just hopes she'll regain it."
Diana, from Blackburn, is the bookies' favourite to win the ITV contest - and a £1million recording contract with Simon Cowell's label Sony BMG.
Tomorrow the finalists will sing Mariah Carey hits before being joined on stage by the US diva
