She most recently scrapped her 10-date U.S. tour earlier this month (Oct11) over fears her vocal cords could be damaged for good if she did not take time to recuperate.
The singer recently gave up cigarettes, but she insists it is her off-stage talking which has been straining her voice, rather than her bad habit.
She tells Britain's The Sun, "Smoking is not the reason I got laryngitis – it was because I was talking too much. I damage my voice offstage, not onstage.
"Onstage I am fine as apparently I am technically great, but when I talk I damage my voice big time. I have got screwed into giving up smoking. If I wasn't a singer I still would be smoking 25 a day."
