The X Factor categories have been revealed and they've got a mentor, but who's the strongest of the lot?
Sunday evening saw bootcamp take place before the acts were split up into their four categories after being cut down to 60 or so performers: The girls, the boys, the groups and the Over 25s.
The singers in each category were then placed in a room before it was revealed which judge would have which category.
First to find out was the girls who had Simon Cowell walk in as their mentor.
Next it was the Groups and - to the surprise of no one - it was Louis Walsh who got put in charge once again.
It was then onto the boys who rushed towards Nicole Scherzinger as she stepped into their room.
That left Sharon Osbourne to mentor the Overs who seemed more than happy with the match.
From here it's onto the Six Chair Challenge where each act in each category will sing for the judges and a live audience at Wembley Arena before their mentor decides which six to take through to judges' houses.
Right now bookies reckon the winner is most likely to come from the Boys or Girls categories, who are tied for favouritism, while the Overs are next and another group winning is fancied as an outside chance.
But who do you think has the strongest category this year? Ahead of the six chair challenge, vote for your favourite in our poll below!
The X Factor returns next Saturday and Sunday night on ITV with the six chair challenge at Wembley Arena.
