The 17-year-old was pictured outside a London studio with the rest of the finalists as they prepared for a day of rehearsing their Fright Night songs for Halloween.
We don't know yet what everyone is singing but should find out on Friday.
Sam, who is mentored by Simon Cowell, has been doing really well in the competition so far, earning praise from the judges for performances including Michael Jackson's 'Earth Song' during last weekend's Legends and Divas Week.
Off-screen, meanwhile, she's had to contend with rumours she's romancing fellow contestant Nathan Lewis, from the band 5 After Midnight.
Speaking to her local newspaper, Tracey told Chronicle Live: "There's nothing going on. Every year contestants get linked with each other but Sam and Nathan are just good mates.
"Sam is getting on well with everyone in the X Factor house, that's just the kind of person she is. Sam has got so much focus and she definitely won't let anything distract her."
X Factor continues Saturday at 8pm on ITV.
