LADY Gaga has revealed her battle with bulimia - and how winning it saved her voice.

The 25-year-old singer said she "purged" so often by making herself sick that stomach acid had been eating away at her throat.

She told a young women`s conference: "It`s easier for me to talk about it now because I don`t do it anymore. I used to throw up all the time in high school.

"Bulimia made my voice bad so I had to stop. The acid on your vocal cords - it`s very bad.

"But for those of you who don`t sing, you maybe don`t have that excuse until it`s too late. It`s very dangerous."

Gaga - real name Stefani Germanotta - recalled how she started making herself ill after eating her dad Joe`s favourite meals of pasta and meatballs.

She said: "I wanted to be a skinny little ballerina but I was a voluptuous little Italian girl whose dad had meatballs on the table every night.

"I used to come home and say, `Dad, why do you always give us this food? I need to be thin`. And he`d say, `Eat your spaghetti`."
