Contestants will be taken to secret locations in Las Vegas, Miami, St Tropez and Athens in the final showdowns before the live shows, according to the Daily Star.
Simon Cowell has demanded that the ITV1 show improve the early stages of the competition and that the Boot Camp and Judges' Houses rounds are more glamourous and tougher than ever before.
Last year's Judges' Houses took place in Ireland, Ascot, Marbella and Australia.
The Boot Camp stage will be super-sized this year and will challenge the acts to workshops, dance classes, songwriting lessons, lightning auditions and masterclasses with special guests. The acts will also sing at Wembley Arena as part of their final task.
Rihanna is among the stars rumoured to be making an appearance at Boot Camp.
