The music manager, who spent 10 years as a judge on the ITV talent show, is in talks with good friend Simon Cowell despite getting the boot shortly before the series kicked off.
It’s thought Louis, who was replaced by Radio 1 DJ Nick Grimshaw, will be sitting in an area away from the other judges as he provides commentary on the acts.
“He will be a neutral fifth judge who will sit in a special place away from the other judges to provide his own unbiased comments on the contestants,” a source told The Sun.
“It’s a massive coup for Louis who is also going to sign a deal with Simon to help launch Ireland’s Got Talent as a judge.
“We know Nick will come into his own on the live shows because of his experience as a DJ, but we think Louis will be a great addition.”
It’s also thought the format for the live shows will be changed.
A source said: “Some of the bosses also like the idea of scoring singers, it was something that was almost brought in during the 2014 series for the live show.
“They would not use paddles, otherwise they would be accused of copying Strictly, but scores would show how people improve each week and would be another thing viewers would comment and discuss.”
