Celine Dion has refused to sing with Sam Bailey on 'The X Factor'.
The Canadian singing sensation allegedly turned down TV bosses' request to perform a duet with the fan favourite during the live final later this month.

The 45-year-old star, who previously appeared on this year's live shows in a pre-recorded performance, declined on the grounds she was too busy, according to The Sun newspaper.
A new artist has been found to partner with prison officer Sam, who has never been in the bottom two, and the line-up of the celebrity duets will be confirmed next week.
The duets have become an integral part of the ITV show, with memorable performances including Alexandra Burke singing with vocal powerhouse Beyonce and 2010 winner Matt Cardle teaming up with Rihanna.
The live finals, which take place on Saturday 14 and Sunday 15 December from Wembley Arena in London, will also see a host of famous faces performing on the stage.
