BBC One bosses have axed Rob Beckett and Geri Horner singing contest All Together Now in a surprise move.
The gameshow debuted last year, quickly becoming one of the channel's most successful new entertainment formats.
It involves hopefuls performing in front of one hundred judges - who are all vocalists from various facets of the music industry.
If the judges like what they hear, they stand up and sing along. The more that join in, the higher the contestant scores.
The winners of the weekly heats return in the grand final to compete for a £50,000 prize.
Comedian Rob was the presenter, while Spice Girls star Geri was captain of The 100.
However, while All Together Now was popular with viewers - rating at around the 4million mark - the Beeb has decided not to bring it back for a third run.
A spokesperson for the broadcaster confirmed: "We would like to thank Rob and Geri and all members of The 100.
"The award-winning format is now on air in 14 countries and the BBC is delighted to have played a part in bringing this unique singing show to the wider TV world.
"We would like to thank the production team for all their hard work in launching such a successful format."
The first series of All Together Now saw Michael Rice crowned the champion after scoring a huge 95 points.
He went on to represent the UK at the Eurovision Song Contest last month, but he finished in last place out of 26 finalists.
Shellyann Evans won series two earlier this year after all 100 panellists backed her for victory.
A celebrity special also aired at Christmas, with EastEnders actress Laurie Brett triumphing over the likes of Gemma Collins and Alison Hammond.
A source told The Sun: "The show was good fun and seemed to rate well. The BBC commissioned a second series, so clearly saw some promise in it.
"But after two airings and a celebrity special, they’ve decided to leave it there.
"They thought Rob and Geri were a great team and are now seeing what else they can do with them."
