Caroline and Olly kicked off filming for the series this morning as auditions hit Manchester.
There were crowds of thousands queuing up to sing with Olly and Caroline on hand to chat - and take the obligatory selfies - with the wannabes ahead of the auditions.
The pair had arrived at try outs in the city driving an X Factor van, before reacting to the crowd: "Wow this is crazy!"
Olly added: "Six years ago I started at an open audition just like this in London".
Those that impress at today's auditions will now have a tense wait until later on in the summer to find out if they will get to sing for the judges, whoever they may be.
While Olly and Caroline are confirmed as hosts, nothing is currently confirmed when it comes to the judging line up for this year's series.
There have been various reports suggesting both Mel B and Louis Walsh have been axed, with rumours that Demi Lovato and Louis Tomlinson could be set to join the show, however nothing is official.
The X Factor will air on ITV in the autumn.
