The boy band - Marvin Humes, Oritsè Williams, Aston Merrygold and JB Gill - revealed in a statement that they would be going their separate ways following a final album and tour.
The lads said: "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."
JLS shot to fame on The X Factor in 2008 and they have been one of the ITV1 show's most successful acts. Sob!
