According to The Mirror, Cheryl has been poorly all week as she fights a fever and a throat infection, meaning the 31-year-old has been keeping in touch with act Lauren Platt by phone.
She took to Twitter to explain her absence to fans, writing: "Sorry for my absence on here the past few days. I have been so sick. Trying to be better for sat."
Speaking about tonight’s live show, a show source told The Sun: "There's a real chance she'll miss it."
The remaining X Factor acts will take on Elton John and Whitney Houston songs as they battle it out onstage.
