Total halloween outfit goals.
The songstress - who was joined by fellow contestants Sam Lavery and Emily Middlemas at the event - took time out of rehearsals to glam up in this skin-tight bodycon playsuit that drew attention to her fabulous legs.
Gifty oozed a whole 'loada sass in a pair of thigh-high boots and glitter-splashed cat ears, but it was her feline-inspired make-up that really stole the show!
Never one to blend in, Gifty went all out and donned a pair of very convincing cat-eye contact lenses (creepy but so cool!) and she showed off her face-painting skills with seriously bushy brows, a flawless smokey eye and whiskers to boot.
She wore her blonde 'do in two 90s-esque buns and posed up a storm alongside guests such as Cara de la Hoyde, Nathan Massey and TOWIE's Chloe Lewis.
Gifty may have blown us away, but she found competition in Love Island star Olivia Buckland - who also rocked up to the bash as Catwoman! Just don't ask us to choose who wore it best - they both looked AH-MAZING.
This week's theme on X Factor is Fright Night, which caused a bit of a stir when the jukebox selected it last weekend. Fans pointed out the coincidence of a spooky theme randomly being chosen so close to Halloween, although, several people associated with the show have come out to deny a fix.
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 wheel. 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."
We can't wait to watch!
