Pop legend Cher "lives like a nun" during her Las Vegas run of concerts and doesn't speak for days on end - because the dry desert atmosphere could wreck her singing voice.
The singer has taken up residence in the Nevada's Sin City, performing regular shows at Caesar's Palace Hotel & Casino.
But Cher insists she isn't able to enjoy the fun on offer in Las Vegas, because just opening her mouth could ruin her voice.
Instead, the Believe hitmaker spends her days communicating with friends and family via email and text messages.
She says, "I didnt anticipate the dryness getting to my throat the way it does. So when Im in Las Vegas, I have to kind of live like a nun and not talk during the day.
Its so hard for me, I just really have to think about it and just not speak, but I have to remind myself about 100 times a day, because Im not the kind of person that doesnt want to talk.
So I text and I e-mail, which is kind of the only saving grace.
