Fleur will go head-to-head with fellow finalists Ben Haenow and Andrea Faustini on Saturday night in a bid to be crowned winner of this year's show.
Along with travelling around the country in their own 'Battle Buses', the three singers have taken part in a new photo shoot - and it's fair to say Fleur has pulled out all the stops!
The 26-year-old has stripped off for her picture and is leaning on a white table against a white backdrop. The contestant's arm is covering her modesty and she is sporting a chunky silver necklace and large hooped earrings.
Meanwhile, both Ben and Andrea have kept their clothes on for their pictures. While Italian singer Andrea is dressed in a quirky outfit, including a patterned T-shirt and turquoise socks, Ben looks like a professional rocker as he relaxes on the floor.
After sailing through to the finals last weekend, it's fair to say all three hopefuls are having a very busy week!
Yesterday, Ben's Battle Bus pulled into a branch of Sainsbury's in Croydon and he surprised his mum, who works on the checkout at the supermarket.
Fleur has also paid a visit to her hometown of Walthamstow, London, while Italian singer Andrea parked up in London's Leicester Square with his mum to perform to the crowds. Given that he couldn't fly back to Italy to see his family, we think this was a pretty cool alternative!
This weekend's live shows look set to be both nail-biting and jam-packed with entertainment. On Monday, The X Factor announced which stars would be performing, and the list includes Sam Smith, One Direction and Demi Lovato.
We can't wait!
