The boyband have begun writing the follow-up to 2012's Evolution, despite the record only being released back in November.
"We've already been in the studio a few times this year, which is mad as its only January," Aston Merrygold told Digital Spy.
"We go into hard writing in the next month or two, and then get creative in the studio. We just want to keep the albums coming and that's what we're going to do."
Merrygold also revealed that JLS are unlikely to release a new single from Evolution, following the poor performance of their recent double A-side singles 'Give Me Life' and 'Hold Me Down'.
"It would be great to release another single from this album, but I'm not sure we're going to. It's about getting creative and getting back in the studio," he added.
Merrygold is currently a judge on Got to Dance, which next airs on Sky1 this Sunday (February 3) at 6pm.
