Nicole Scherzinger, Gary Barlow, Sharon Osbourne and Louis Walsh reunited in London on Thursday (8 August) to put this year's hopefuls through their next batch of auditions in the process.
'Boomerang' singer Nicole looked as gorgeous as always in a fire engine red skirt teamed with a monochrome halterneck and sky high black heels.
She wore her chestnut hair in a sexy updo (which we spotted yesterday and raved about in detail!)
Sharon, meanwhile, had just jetted in from the US and stuck to her favourite black. We wonder if she brought adorable teacup Pomeranian Mr Chips along?!
This year's X Factor has seen a sneaky audition twist – contestants had to pass both an intimate audition in front of the judges and an arena audition in front of thousands in order to make bootcamp stage.
From there, the lucky few who succeed at bootcamp will then be jetted around the world for judges' houses before the select group for the live shows are chosen.
It will be a bittersweet season for Louis fans, however, as he's confirmed he will leave the show this year. After ten years on the panel as an original judge he said last week he's ready to focus on other projects.
Sharon will also leave at the same time. She previously said she'd only returned to the show for one season to celebrate its tenth birthday.
