Leona Lewis' silent protection
Leona Lewis is so terrified of being stricken by an illness that would affect her sining ability, she barely speaks offstage.
Leona Lewis refuses to say more than a few words to people because she wants to protect her voice.
The 'X Factor' winner is so terrified of losing her voice she never shouts and keeps small talk to a minimum.
She said: "I get scared of things not panning out the way I want them to. I wonder what I'd do if anything happened to my voice. That's why I look after myself so much.
"I'll say, 'I can't talk to you for too long', and 'I can't do this or that because I'm doing a show'. I'll miss nights out because I can't be talking over loud music. I get panicked in case something happens."
But the 24-year-old star is not worried about losing her fame and fortune - she just loves singing, and would be devastated if she couldn't do it anymore.
She said: "Singing is an escape. When I sing, I go somewhere else, out of this world. It's another place where I'm free to do whatever I want. It's like a dream. It's my favourite colour, pastel pink, and there's just me there."
Leona isn't the only singer who goes to extremes to protect her voice - Mariah Carey doesn't say a word for two days before a concert.
The 'Touch My Body' star previously said: "Before a big show I have to do 'vocal rest' where I'm not allowed to speak for two days. It's so boring having to write notes to everyone! I need Stephen Hawking's voice machine for when I'm on vocal rest.
"I'd like a machine where I can just think and it comes out in a robot voice - that would be amazing!"
