Aston Merrygold's mother immediately assumed he had got a girl pregnant when he told her he had ''news''.
The JLS singer text his mum to warn her he had something big to tell her - that the boy band have decided to go their separate ways after their 'Goodbye' tour in December - but within ''seconds'' she replied asking him which woman was expecting his child.
Speaking to The Sun newspaper in a joint interview with his fellow bandmates - Marvin Humes, Oritse Williams and J.B. Gill - Aston said: ''The first person I told about our plan to call it a day was my mum.
''First it was just a text saying, 'I've got some news'. She replied in seconds with, 'Who is pregnant?'
''So I called her and told her not to worry, and that me and the boys were going our separate ways.
''She is hard to shock but she was obviously upset. The whole experience was lived by all our families as much as us.''
The 25-year-old singer - who has just finished his first season as a judge on talent show 'Got To Dance' - admits he won't miss the ''pressure'' that comes with being in a boy band, but has set his sights on becoming an actor when the group hang up their microphones at the end of the year.
Marvin - who recently landed a regular radio show on Capital FM - is also keen to remain in the entertainment industry by expanding his DJ-ing, becoming a music producer and dabbling in TV presenting, while Oritse is also ''looking at doing various TV projects as well as music projects''.
However, J.B. Gill is keen to veer away from his showbiz lifestyle and plans to buy a deer farm in the Scottish Borders to work on when he is finished with the group.
The 26-year-old singer - who has also spent 18 months preparing his other farm in Kent, South East England, for livestock - said: ''I'm just focusing this year on the farm. I'm in the middle of trying to set up a place in Scotland deer farming.
''The farm for me is an ongoing thing. It's an investment. It's something that's different and close to my heart.
''My dad's involved in it with me, so I guess it's a father and son thing that we can get stuck into.
''At the point whenever I have children it'll be something they can carry on.''
