Marvin, Aston Merrygold, Oritsè Williams and JB Gill have put together a montage of their career for the visual, including scenes from The X Factor and their concerts.
It also features clips from their trip to Africa for Comic Relief, along with their performance at the Diamond Jubilee, scooping awards at the MOBOs and a group skydive.
Rochelle shared the video with her fans on Twitter today (4 October), adding that it had made her teary. Aww!
She tweeted: "Have deffo cried at this! So proud of my boys @JLSOfficial. Love you all lots xxx #emotional."
JLS rose to fame after starring in the 2008 series of The X Factor. Even though they lost out to Alexandra Burke, the lads went on to have a hugely successful career.
But in April, JLS announced they were splitting after six years together.
Along with the release of 'Billion Lights' on 10 November, Marvin, Aston, Oritsè and JB are releasing their final album Goodbye - The Greatest Hits on 18 November.
They will then embark on a final UK arena tour, beginning in Belfast on 1 December, before going their separate ways. Sob!
