Simon Cowell still angry One Direction did not scoop X Factor in 2010
Simon Cowell says One Direction could be the real stars of The X Factor final because the hugely successful boyband still think they are in the competition.
The mogul said he is still angry they did not take the prize in 2010.
He said: "I was talking to the guys from One Direction all day long yesterday while they were in rehearsals and they are doing something special and its quite amazing they have come off this stadium tour this year, but actually their focus is absolutely what they're going to do on the night because they still think they're in the competition."
One Direction are just one of the big names including Sam Smith and and Ed Sheeran who are performing at this weekend's final.
