The 17-year-old channelled her inner goth and totally pulled off this creepy Addams Family look for the Kiss FM Haunted House Party at the SSE Arena.
P.s. check out that cheekbone! Hello, contouring!
The X Factor finalists are usually so busy at rehearsals they're not seen at many events while the series is on air, but producers gave them the go-ahead to enjoy themselves on Thursday, ahead of this weekend's Fright Night.
Other X Factor stars at the party included Saara Aalto, Ryan Lawrie, Emily Middlemas, Gifty Louise and last year's winner Louisa Johnson, as well as former Xtra Factor co-host, Kiss FM DJ Melvin Odoom.
An excited Sam nabbed a photo with Louisa, who is no doubt a big inspiration to her: Louisa was just 17 when she became the X Factor's youngest ever winner last year, so Sam will be hoping to follow in her footsteps.
Louisa, who released new single 'So Good' on Friday, performs on Sunday's results show.

This week's Halloween theme on X Factor is Fright Night, which caused a bit of a stir when the jukebox selected the theme last weekend. Many fans pointed out the coincidence of a spooky theme randomly being chosen for a spooky night.
But several people associated with the show have come out to deny that's the case.
Judge Nicole Scherzinger and spinoff show host Rylan Clark-Neal both insisted it had been a random choice, while creative director Brian Friedman branded it a "spooky coincidence."
Rylan said on This Morning: "I think personally it's not fixed whatsoever. I was actually standing at the side of the stage. That jukebox is pretty much an empty shell with a genuine whee. I had asked Simon on Xtra Factor, 'is there a little man in there?' There's not! I've had a good look and it's an empty shell with a wheel."
So far, only two contestants' Fright Night songs have been revealed: Honey G is doing the Men In Black theme song, while Saara Aaalto is tackling Lady Gaga's 'Bad Romance'.
X Factor continues Saturday at 8pm on ITV.
