But Simon Cowell didn't seem as thrilled to take the Over-25s again, despite winning with the category last year. ‘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,’ Cowell wrote on twitter.

The 53 year old had been campaigning on social media last week to have a chance at mentoring another category. ‘I mentored the overs last year and had the winner and the runner up,’ Cowell tweeted on Sunday. ‘Great singers in this category, but I would be keen to see how another judge would do with the overs this year!’

But despite the revamp the series suffered its lowest launch night ratings ever. According to The Mirror, Saturday’s show only brought in 7.11m viewers, a drop of nearly two million from last year's launch show.
