Both boybands will feature on this year's X Factor charity single 'Wishing On A Star', which is a cover of the Rose Royce 1978 classic.
However, both groups have spoken and are to put some time aside to go into the studio to try out new ideas.
Talking about recording the charity cut with One Direction, JLS's Aston Merrygold told Capital FM: "It won't be the last time.
"We've got a couple of ideas, we've been in the studio for the past couple of weeks because album four is underway."
He added: "We just can't stop writing at the minute, so we're going to have a little conversation with the boys and we've got some ideas to happen."
Oritse Williams concluded: "Can you imagine the fans? It's going to be crazy. I think every girl in the country will be there."
JLS's new album Jukebox was released in the UK today, while One Direction's debut LP Up All Night will be available on November 21.
