X Factor stars Janet Devlin and Sophie Habibis have teased their "spooky" song choices for this weekend's Halloween special. The girls, who have been Skype-ing with their mentor Kelly Rowland in LA, hope to shock viewers with their performances on Saturday night.
Sophie revealed in her latest video diary: "This week's song is going to be very spooky!
"It already is, but we're going to add to it... and I think you will be very freaked out."
Meanwhile Janet, who said she'd love to duet with the Red Hot Chili Peppers if she made the final in December, promised a "well known" song with a spooky twist.
She told fans: "I've taken a really, really well known song and because it's Halloween, I've twisted it and made it spooky."
