We saw on Sunday night's latest show how Tulisa split MK1 up, asking them to ditch member Will Baker after the trio performed Read All About It at the auditions in London.
"Okay, do you want the good news or bad news? The good news is, that’s rap… but you’re either going to have to become a duo or find another member," Tulisa told the group. “I need to understand what your involvement is in the band [Will]. I can’t hear her [Charlie]‘s beautiful voice. It stopped me from enjoying the song.”
Nicole agreed: “Some of your notes are flat, Will, you need to be able to match Charlie.”
“You look the band’s accountant who has come on stage for a song,” said Gary to Will. “You should not be on stage with the band.”
With it being a choice between leaving the competition or Will leaving the group, MK1 continued through to boocamp as a duo.
It's now been revealed that Will is working with Justin Edwards, who was forced to aplogise in court over leaking a sex tape involving him and Tulisa.
However an X Factor source told the Daily Mirror: “Justin has been booked into Will’s studio to record over the next few weeks.
"Tulisa wouldn’t have known about it at the time of X Factor filming.”
Tweeting after the weekend's show, Will said: "Big up @officialultra [Justin Edwards] currently producing a massive record with him.”
