And he is said to have told them that, since it's Halloween themed this weekend, there's going to be a twist.
He said: "There's going to be another double elimination again this weekend, and the difference is there is going to be a twist.
"And the twist is, on Saturday, the person with the lowest vote is going to leave the show. No sing off, just whoever is in the bottom is out. And there's a sing off on Sunday. So no second chances."

Simon told the contestants the twist is a wake-up call to make them realise they have to do better, after it was reported he was disappointed with the standards this year.
He added: "And I think you've got to understand what I'm saying isn't just words, it's reality, you've all got to build up your game now and you've got to be best you've ever been because this is really what the music business is like."
A source told the Mirror: "He hasn't been very impressed with the sing offs so far and feels there isn't any excuse for people performing badly."
What do you think of the twist?
