Talking exclusively to omg! this morning, the urban duo slammed the judge for not saving them on Sunday's show despite branding the act 'schermazing' after their Saturday night performance.
Charlie told us: "We're a bit vexed with Nicole, she should have had our backs what was she doing? She gave us a 'schermazing' then was like 'you know what you're not schermazing tonight'."
"Nah, dead. She used to be my favourite as well but not anymore!"
That's one less album Nicole Scherzinger will be able to shift in the future then.
Mentored by Louis Walsh, the urban act faced some criticism last week when the judges thought they had lost some of their edge after performing 'I Want You Back'.
When asked if they thought someone like Tulisa would have been a better mentor for their act, MK1 were adamant that they were happy to have Louis.
Charlie said: "I don't think anyone would have been a better mentor, I think they would have been different mentors and I don't feel we got the bad hand with having Louis."
"Louis did understand us despite what the papers and the public said. And he did behind closed doors, he's not the same guy you see on TV, he does understand and he does listen."
"He's a really down to earth guy, Tulisa would have just pushed us at a different angle."
Sim chipped in: "She probably would have just made us a bit rawer and a bit edgier."
Charlie then added: "But that might us pushed us out in the first week."
As to who they think will win the show, MK1 have a feeling that Ella Henderson will take the title due to both her talent and the amount of coverage she's been receiving on the show and in the press.
Charlie explained: "I feel like Ella has a good chance. They seem to be bigging her up all over the press and the X Factor likes to put her in the limelight."
"She's fantastic. She's a 16 year-old girl with the heart and soul of a 20 year-old woman. She's a quiet girl backstage but she's only 16."
As for MK1, the two told us that they will be going back into the studio and gigging very soon.
Sim admitted: "We are going to be gigging around as much as we can, get into the studio. Just pick up where we left off before we even applied for the X Factor. Just start cutting tracks and pick up the momentum."
"Looking back at those best bits we were like 'yeah it's been a wicked journey, it's a wicked platform'."
