Considering how sick she is, we're no surprised!
Her spokesman said:
"Cheryl Cole is making good progress but following medical advice she will not be able to take part in X Factor's boot camp stage or perform at V Festival."
It is not known whether a guest judge will step in, but ITV just wants to make sure Cheryl is healthy.
The network said:
"Cheryl will not be attending The X Factor boot camp later this month. Our priority is to ensure Cheryl is fit and well before she returns to work and to give our contestants a fair and proper opportunity to compete in the show."
The pop star was released from intensive care at University College Hospital in central London on Friday and taken to a nearby clinic to continue recovery.
"Even now she can't talk. She drifts in and out of consciousness and when she comes round all she can do is sob," claims a source.
We hope that's not true, but it will definitely be at least two months before she resurfaces.
Poor thing. Rest up, honey.
