Girls Aloud star Cheryl Cole has said that she is concerned that her singing voice may have been damaged by her recent battle with malaria, a report has claimed.

Sources claimed that the 27-year-old "lost her voice" for a period of five days earlier this month while in hospital fighting against the deadly disease.

An insider told a tabloid newspaper that the X Factor judge is worried that she might not be able to sing as well as she could before contracting malaria.

A source told The Sun that the Geordie lass has been drinking hot water with honey, cinnamon and lemon to soothe her damaged vocal cords.

The insider revealed: "Doctors have told her that it will come back, but she's full of worry."

Simon Cowell recently confirmed that Cheryl was on the road to making a complete recovery from the illness.

The entertainment mogul told GMTV that he had been talking to Cole via text message.

He said: "The worst is over. The texts are getting increasingly feisty so she is on the mend."
