British pop star Jessie J avoids drinking alcohol on a regular basis in a bid to preserve her singing voice.

The Price Tag hitmaker, who announced on Friday (05Jul13) she has quit her role on Britain's The Voice, admits she hasn't given up drinking completely, but moderates her alcohol intake to stay as healthy as possible.

She tells Britain's The Sun, "You are under pressure to always be healthy, because there are days in your diary that people have been looking forward to for months... I do drink when I go out, but I don't really drink very often. I have a glass of wine or I have a cocktail when I go out with my friends and that's Ok... The odd one is fine, but as an artist, it's not really my thing. Alcohol is very acid based and when you see a voice doctor when your voice is tired, the first thing they say is 'stop drinking'.

"As a piano player you wouldn't dip your fingers in acid, and alcohol does that to your voice."

Jessie J also insists her job has ruined her social life as she rarely has time to go out with her friends, adding, "I have literally sacrificed so much in my life where I don't really get to see my friends that much. I don't go out very often, because I want to stay healthy while I am working and I think it's important. But I also think that sometimes I do need to let my hair down and stay up late."
