Sarah Harding has walked away from her performance in Ghost for a while, just days after its debut in London.

The former Girls Aloud star was unfortunately slated by Ghost fans over the past number of days, but that's not why Sarah is holding back.

According to The Mirror, the singer is sick and needs to rest…

"Sarah went to see the doctor today who diagnosed an upper respiratory tract infection," her spokesperson said.

"She's been really pushing herself over the past three weeks, rehearsing solidly for the show and making sure her performance is perfect.

"Fans of Sarah will know that she is a true grafter and that she always pushes herself to the absolute limit, but it's all caught up with her. She still has three months of nightly performances to get through, and she's dead set on giving it her absolute all."

We'll just have to wait to see what happens!
