The Sun newspaper's showbiz editor Gordon Smart spoke to Daybreak about JLS' rumoured split.
He said: "Normally in these kind of circumstances there has been some kind of fallout," he added, "In this case it is genuinely an amicable split.
"They're very mature, they've had everything planned from day one and I think they've just made the decision that it's best to part before there's a fallout."
Fans of JLS are in shock over the news that the boyband announced they are to split. They said after 5 number ones it is time to separate.
