Here's are the groups set to perform on Let It Shine this week, singing with a number of musical super stars.
Take That's Gary Barlow, Spandau Ballet singer Martin Kemp and former X Factor judge Dannii Minogue take up a role on the judging panel for Let It Shine.
The show is on the hunt for five guys to perform in a new stage show based on the music of Take That.
This week the Top 40 boys from the audiitions will be split into groups of eight who will take to the stage in all singing, all dancing performances with some familiar faces.
The boys will seek to prove their worth as they collaborate with some of the UK’s most-loved artists with spectacular staging and one big song after another.
The guest performers revealed are Busted, Beverley Knight, Melanie C, Olly Murs and Kaiser Chiefs.
After the performances, the judges will then select five individuals from each group of eight to go through to the live finals which begin next Saturday night.
Here are how the groups are organised...
