The X Factor 2016's Six Chair Challenge kicked off today at Wembley Arena.
Simon Cowell was up first with his category as the remaining contestants performed for a place in the next round, judges' houses.
A crowd of thousands packed out the venue although they were kept waiting a while with filming kicking off four hours later than scheduled.
As the budding performers rehearsed, new Xtra Factor co-host Rylan Clark-Neal reunited with his former mentor from the show Nicole Scherzinger backstage.
Rylan returns to The X Factor this year to front ITV2 spin-off the Xtra Factor alongside funnyman Matt Edmondson, with the pair replacing Melvin Odoom and Rochelle Humes.
Meanwhile, the judges' bizarre paper mache doubles hit the red carpet outside the arena for a VERY unusual photocall.
Once the six chair challenge kicked off it seemed as though little had changed to the format from past years despite critics branding the process "cruel".
On stage are the six chairs, representing the available spots at judges' houses.
The acts in each category will perform once, one after the other, for all the judges and a live audience having picked what they think is a killer song.
All the judges will comment - and the audience are sure to make their views known - but it'll be the mentor of that category who alone decides whether to give them a seat or to send them home.
However, even those given seats aren't necessarily safe. The mentors can choose to swap those in a seat out for another act if they feel others performed better.
Only once all the acts in the category have performed are the six in the seats finalised, with those lucky singers left sitting down through to the next round.
The X Factor 2016 will air later this year on ITV.
