Chart-topping boy band JLS have shocked fans by announcing they are to split after a string of hits and said: "It has been the most incredible journey."
The group, whose hits include Everybody In Love and The Club Is Alive, said they had been agonising over the decision for months.
The quartet, which found fame on The X Factor after featuring in the 2008 series, will give a farewell tour in December and said they wanted to "end on a high".
The foursome - Aston Merrygold, 25, Marvin Humes, 28, Jonathan "JB" Gill and Oritse Williams, both 26 - had fulfilled their initial recording deal, but did not want to sign a further contract committing them to several more albums.
Their success has led to several spin-offs with the group launching their own range of condoms and Merrygold has taken a judging role on Sky's Got To Dance series. Gill has developed an interest in farming and recently featured on the BBC's Countryfile as he learned more about agriculture.
After their run of five number one hits and two Brit awards, they announced their exit with a statement to fans which said: "We wanted to make sure that you heard it from the four of us, that we have decided to bring our time as a band to an end.
"It has been the most incredible journey over the last six years and we have achieved more things than we could have ever dreamed possible. Thanks to all of you guys, your support, your dedication and your love, you have changed our lives forever and we wouldn't be where we are today without you.
"Goodbye: The Greatest Hits Tour will be the last time that we will perform together as a four and we want to make sure that this tour is the best ever and that we end on a high! We will always remain brothers and friends and we will always be your boys."
JLS, who finished second to Alexandra Burke on The X Factor, will also release a best-of album to coincide with the finale shows. During their career, the band have sold more than 10 million records, had five number one singles and won two Brit awards in 2010, as well as five Mobo Awards.
In an interview with The Sun, Merrygold said: "We are still the best of friends and always will be - but this is the end."
