A made-up pop star could be about to beat X Factor winner Leon Jackson to the top of the charts.
Leon has released his new single this week, but a track from a singer called Geraldine McQueen is only just behind him in sales.
But Geraldine is not a real person. She is really comedian Peter Kay, and is a character from a comedy TV show.
The programme made fun of TV talent shows like the X Factor, and now a joke song from it could have the last laugh.
The programme was made to look just like the final episode of the X Factor, and was called Britain's Got The Pop Factor And Possibly A New Celebrity Jesus Christ Soapstar Superstar Strictly On Ice.
At the end the winner of the show sang a track called The Winner's Song, which sounded a bit like the kind of tune the winner of the X Factor tends to release in time for Christmas.
But the people behind the made-up show decided their song sounded so good that it would be released, and now it could sell more copies than the the type of track it's poking fun at.
