X Factor bosses are hoping record-breaking chart star Adele will appear at the show's final, just weeks after her voice-saving surgery.
She has been pencilled in to appear at Wembley Arena for the finale of the ITV1 series next month.
However the date depends on whether she has had enough time to recover from the operation she underwent in the US earlier this month to repair a vocal cord haemorrhage.
She has already said she is "on the mend" in a blog recently. The condition led to a number of gigs being cancelled and had threatened to ruin her voice permanently.
A programme source said: "She's one of the world's biggest stars so we'd love her to perform at the final - we are just hoping she recovers in time."
The X Factor final takes place on December 11, with a number of other big name acts being lined up.
Earlier this year Adele spoke of her unease at playing arena shows and said she had turned down gig deals potentially worth millions of pounds because she did not feel comfortable performing them
The X Factor quarter finals theme has also been confirmed - Guilty Pleasures and Heroes.
All five acts - Little Mix, Janet Devlin, Amelia Lily, Misha B and Marcus Collins - will have to sing two songs on Saturday night for their survival.
Tulisa Contostavlos's girl-group Little Mix have emerged as the bookmakers' new favourites to win the competition, over the past week.
