Irish 'X Factor' star Mary Byrne has reportedly lost her voice after being hit with throat problems again this week.
According to the Daily Star, a source said: "She could not even finish rehearsing her song yesterday."
"She is off to the doctor today to try and get it all sorted."
The singer stayed at home last night while all the other contestants attended a fashion show together.
She also suffered from throat problems at the beginning of the live shows.
