Simon Cowell has reportedly once again overhauled bootcamp, this year making it the toughest stage of the competition ever. The five day 'musical workout' kicks off on August 14, and will include dance classes, song writing sessions and a performance in front of some 7,000 fans at Wembley Arena.
As TellyMix revealed last month, this year the audience for the bootcamp stages will return for only the second time in the show's eight year history.
There will also be 'lightning auditions', with hopefuls asked to learn new tracks within an hour, and also special guests coaching the contestants - with superstar Rihanna already lined up.
The bootcamp will whittle down the 200 or so remaining singers down to just 32, eight in each category for judges Tulisa Contostavlos, Kelly Rowland, Gary Barlow and Louis Walsh.
The judges and the contestants will then jet off around the world to decide their four live finalists.
A source told the Daily Star: “Simon may not be on X Factor UK this year but he is making sure it keeps its sparkle.
“He’s really putting the pressure on. He wants to boot camp to be a boot camp and not a holiday camp. So that means making it longer and tougher.
“And he felt the judges’ homes were a bit flat last year so he wants more stunning locations.”
The X Factor 2011 starts on August 20.
