X Factor group The Cutkelvins could become a four piece by the end of the year.
Right now the current trio are made up of siblings Jay, 24, Kyle, 23 and Shereen, 20.
However their younger brother, 16-year-old Brandon could join their ranks.
“Our youngest brother - he’s going to be joining at the end of the year," Jay told The Sun On Sunday newspaper.
Shereen said: “He’s turning 17 on Christmas Eve so he’s gonna bring all the young girls in! He’s already got quite a lot of followers! Just for looking good. He’s the good looking Cutkelvin."
Kyle added: "He’s not even opened his mouth yet and he’s got more followers than all of us!"
Shereen even revealed that Brandon had already started "training" to join the group.
"He's in training right now...he came to live shows and we asked him what he thought and if he'd be able to do it and he said yes," she explained. "So he's willing to do it and we want him here as well.
"Brandon sings and he raps... and he'll be the one taking all the girls probably."
The Cutkelvins are currently one of the six remaining acts on this year's show, last night again impressing viewers and judges to make it through the latest vote.
Following their latest live outing on Saturday night, The Cutkelvins are now one of six acts left in the competition's final stages ahead of the semi-finals.
