Cheryl Cole is still being treated by doctors after spending her fifth night in hospital with malaria.
The final round of X Factor auditions will go ahead in Manchester without her as she is ordered to rest.
Doctors think she caught the potentially deadly disease on a luxury break to Tanzania in Africa.
She was whisked away on holiday in June by close pal and rumoured boyfriend Derek Hough.
The 25-year-old, who won Dancing with the Stars with Nicole Scherzinger and also appeared in the video for Cheryl's single Parachute, is thought to be keeping a bedside vigil.
His stepdad Aaron Nelson has told The Sun he blames himself: "Derek feels guilty. He is very distressed about all this."
