Earlier this year was the first ever run of Gary Barlow's Let It Shine with the show ending in January.
It was Five To Five who won the first ever series, securing a role in Gary's new stage musical The Band, based on the songs of Take That.
Talks were held for a second series with Gary's fellow judge Martin Kemp previously saying: "We’ve talked about [a second series] and we’ve got some ideas. I’d love to do it again because it was so much fun."
Dannii Minogue also said she'd love to be involved in a second run, saying: "I'd love to be a part of it again, I've just been very vocal that the end prize has got to be as good as this one.
"So if they find something that's gonna be as fantastic a prize, then I'd definitely love to be involved."
And it's the lack of a good prize that means Let It Shine won't return in 2018.
"The show was a huge success in many ways but the concept for a second series just wasn’t quite there yet," a source told The Sun newspaper today.
Explaining that 'years of work' went into the first series, the insider added: “Gary in particular wants to make sure that if it does come back, proper time, effort and ideas have gone into it. There’s a danger of undoing the good work done this year by rushing into another series."
A spokesperson for the BBC told the tabloid "the door is open" for a another series but there was no plans for the show to air in 2018.
