Kazeem Ajobe has apparently been banned from future performances after fighting with his bandmates backstage.
The trio of singers - who finished fourth in last year's show - have had a rough ride on the show.
They first auditioned in 2012 but Kazeem's visa issues ruled them out of going past judges' houses.
Last year the same problems saw Kazeem quit before judges' houses before re-joining the group for the live shows.
But now once again Kazeem has left the band leaving Sterling Ramsay and Joseph Thomas to conclude the tour as a duo.
A show source told the Daily Mirror newspaper today: “There was trouble backstage, a bit of a scrap and a big row. Bosses decided Kazeem was to blame.”
The X Factor live tour is currently in Liverpool and will move this week to Leeds and Nottingham.
Next week will see performances in Bournemouth, Brighton and London's O2 arena before the show concludes in Birmingham at the end of the month.
