Having been in their very shoes, Fleur knows exactly how the acts are feeling, and she has a few predictions about who could go far.
In a new interview with X Factor, Fleur said of Simon Cowell's Overs category: "Anton is one of the strongest vocalists in the whole competition, and Max, he's the dark horse. At Judges' Houses, he just came out of no where I think, kind of similar to my journey. I think we should keep our eye on Max, he could do something."
Fleur was mentored by Simon last year where she came in second place, losing out to winner Ben Haenow.
Having experienced being a finalist, Fleur said one singer is particularly impressive - Louisa Johnson. "Louisa seems the most relaxed and comfortable on the stage, I think she's got a lot of potential to go very far. I can't believe she's 17. At 17 I would never be able to do what she's doing right now.
"But I love Reggie 'N' Bollie. I'm supporting them as they are both from Ghana, where my mums from, so I have a place in my heart for them. They are so much fun."
So, has Fleur got any advice for the contestants left in the competition? "I would say the main thing is to stay focused on what you're there to do, enjoy the process and just have fun. Don't get wrapped up in the competition or what the odds are or who the favourite is, as all of that changes and it's irrelevant. Just stay focused on what you're there to do."
Fleur will perform her brand new single 'Sax' on The X Factor this weekend, which is taken from her debut album, Love, Sax And Flashbacks, due for release on 4 December.
