The girl band found themselves in the bottom three last weekend and have been busy working on a performance to wow this Saturday. But everyone needs some R&R too, right?
The group - Caroline, Yasmin, Sophia and Lauren - headed to a plush spa on Wednesday and spent the day being pampered, opting to work up a sweat in the sauna rather than in the dance studio.
Sharing a snap of themselves all wearing bathrobes, Four Of Diamonds told their Instagram followers: "Had a well needed day of relaxation!"
Four Of Diamonds were late the join this year's live shows, having initially been sent home at Judges' Houses. However, Louis Walsh decided to bring them back after Brooks Way quit the competiton in week two.
The group sailed through after their first live performance, however they ended up in the bottom three with Ryan Lawrie and Relley C on Sunday night. Ryan was saved in the public flash vote and Four Of Diamonds were saved by the judges.
This week, Four Of Diamonds have promised a "stripped back performance" for Saturday's 'Fright Night'.
Speaking on ITV1's Lorraine, Sophia said: "We are going to strip it back completely to what you saw at our Judges' Houses, hopefully. I know it's Fright Night and Halloween-ey themed, but it will just be us singing. No fuss."
The X Factor continues at 8pm, ITV, Saturday 29 October.
