The judges found out last night which category they would mentor this year, following a public vote on Twitter. In previous years, it was producers who assigned each judge a category.
And the results this year…
Simon – The Overs
Cheryl – The Groups
Rita – The Girls
Nick – The Boys
Reacting via Twitter, head judge Simon said: "Wasn't the category I was expecting. I did win last year with the Overs so I'm sure we will do great things this year."
Simon mentored Ben Haenow to victory on last year's show.
Meanwhile, a delighted Cheryl Fernandez-Versini couldn't help gushing: "I GOT THE GROUPSSSSS!!! I am so excited!! Thank you so much for everyone that helped me and voted !! I am ready to rolllll!!"
New judge Nick Grimshaw was equally happy to mentor the Boys, tweeting: "We have some stars in that category."
Fourth judge Rita Ora has yet to react to her category, although she did retweet the official X Factor announcement of which judge got which category.
X Factor's latest series premiered at the weekend on ITV, bringing us all the action from the auditions which happened earlier this year. In real time, the successful auditionees are at Boot Camp with the judges this week, where they will find out who goes through to Judges' Houses.
Once again, we'll see the Six Chair Challenge at Boot Camp, with the contestants singing for one of just six spots at Judges' Houses. And then in a major twist, this year's Judges' Houses will be broadcast LIVE from four exotic destinations. That means we'll watch their performances at Judges' Houses live, and find out live who goes to live shows and who goes home.
Before the show started, music mogul Simon had said there was no weak category this year, as the overs, groups, girls and boys all have at least one contestant capable of winning.
"Interestingly, there's no weak category this year. I can see who the winner of each category could be. It could all change, we've only seen them for the ﬁrst time," he said.
He added: "I think this year I also want it to feel more like a competition. Getting it into people's heads that yes you could have a record deal if you come third or fourth, but actually it's a badge of honour to say, 'I won'. That tells me in the real world that they are people who are more likely to do well. I am going to explain that to the contestants, I want ﬁghters!"
