The Beat Again hitmakers split following a farewell tour, which came to an end at London's O2 Arena over the weekend.
The quartet - Aston Merrygold, Marvin Humes, Oritse Williams and JB Gill - took to the stage to perform their hits in front of a star-studded crowd, which included fellow former The X Factor stars Olly Murs, Liam Payne and Niall Horan.
However, the stars struggled through their finale of Everybody In Love when they were overcome with emotion.
A source told The Sun:"Marvin started it during his opening line in Everybody In Love. Aston went to console him before crying at the start of his line. They were in bits."
After the show, Merrygold tweeted: "That hit me like a f**king hurricane! But Seriously from the bottom of my thank u! For now I'll say 'see you later' forget goodbye!"
Humes added: "Just want to say thanks to everyone who came to support us yesterday..it was a very emotional but incredible day!"
