Ivy, aka Ayegee, NAILED her Six Chair Challenge performance to win a seat in the final six of the Overs category last week.
But visa problems forced her to withdraw from the competition when it came to judges' houses in American.
One of the favourites to win, Ivy has revealed how a simple paperwork mistake is why she left the show.
Ivy explained: “The US embassy officer said there's no problem with my papers, but I applied in the wrong visa category.
"So I asked if I’m denied, the officer said no, you are not actually denied. He said 'I advise that you apply for an artist visa instead.'"
She added: "The process took 3 to 4 days and the X Factor team had to travel in two days."
With Ivy out of the competition, Overs mentor Sharon therefore had a free spot in her category and decided to invite back Honey G.
Talking about Ivy’s exit, Sharon said: “I’m really disappointed that Ivy couldn't continue in the competition but I really wish her well.
She added about Honey G: “I thought long and hard about who can take Ivy's place in the competition and I have never received so many calls and texts about an auditionee before.
"She's larger than life, she's fun, she's different to everyone else in this competition... and I love different.”
As for Honey G herself, she explained: “I think Ivy's voice is incredible and she's very talented. She definitely would have gone very far in the competition if she had stayed.
"Obviously it's a great shame she couldn't progress but I'm very lucky and very happy to be back in the competition, a complete stroke of luck for me. I’m not just belting out an amazing voice; I am what is happening right now in the music scene. I’m the whole shebang.”
Honey G will now be competing for a place in the live shows alongside, Samantha Atkinson, James Wilson, Relley C, Christopher Peyton and Janet Grogan.
The X Factor 2016 airs this Saturday and Sunday night on ITV.
