Fleur originally auditioned for The X Factor as one third of girl group Addictive Ladies back in 2005 and after making it through Simon's Judges' Houses round in Marbella, Fleur and the girls were sent home during the live shows.
Now going it alone and back for more, Fleur will take on Simon once again for a place in his final three.
But despite being up against a whole host of younger hopefuls, a confident Fleur believes the overs have never been more "up for" the challenge.
She said: "[The overs are] usually full of has-beens but we're all really hyper and young at heart so we're up for it. We're the biggest kids in the competition. The young boybands will have to keep up with us."
Ooo, boys you have been warned!
Ahead of her Judges' Houses performance, Fleur admitted singing for Simon at his house would be a bit like "deja-vu" for her.
But making sure she is more than ready, the 26-year-old has been rehearsing non-stop.
After feeling like the show's underdog from her first audition, Fleur said it was the kick she needed to make herself work harder for her place in the competition.
Claiming there's no room for complacency, Fleur said: "My feet have been aching because I've been rehearsing so much. I sent myself to my own version of X Factor Boot Camp to prepare."
Two X Factor Boot Camps in one go?! Now, that sounds intense!
