Nicole already appeared on the panel as a guest in the Manchester auditions last week.
Now she will join Simon Cowell and Louis Walsh at the boot camp auditions next Thursday, but X Factor bosses have decided not to film the event live at Wembley Arena as originally planned.
The show's Twitter announced:
"Due to the unusual circumstances, we are not inviting an audience to watch the contestants perform at The X Factor boot camp next week."
Decent choice, but we hope Chezza gets well soon!
