Fans who have been wondering about the off-screen development of 'The X-Factor,' the show will be back in August.

The filming for the 'Six Chair Challenge' has already begun. Each judge has also been assigned the categories. Moreover, starting this year, a new round has also been introduced to the show, which will give its audience the opportunity to watch the contestants in action. This has been possible because of the initial auditions and the Boot Camp, which are taking place behind closed doors.

So, those who attended the Six Chair shooting, first round, have been informed about the mentors and their categories. According to reports, the charge of the Girls has been given to Simon Cowell. This is the first time that this has happened in the show.

Interestingly, in 2006, when he had a female under his wings, he won the show and together with Leona Lewis, he rose victorious. The first season of the USA version also had him mentoring the Girls. And, again, he won with Melanie Amaro.

Judge Nicole Scherzinger has been assigned the Boys group again. Moreover, she also shares a splendid past with her present group. She had bagged the top position, along with Jahmene Douglas and James Arthur in the year, 2012. Ryan Clark, whom Nicole had introduced to the singing arena had finished fifth in the same year. He is now the host of the show.

Another judge who will be repeating her group is Sharon Osbourne. She had the same group in the year 2013. What is yet to be seen is whether she is able to repeat her victory, like 2013 with Sam Bailey.

And, for the sixth time, Louis Walsh will be taking over the Groups in his stint on the show.
