Lady GaGa has revealed that she stopped taking drugs because of her fans.

In an interview with The New York Times, the 'Bad Romance' singer explained that she has been betrayed in the past.

She continued: "I left it behind because I had to. For many reasons, like drugs. It's no secret that I have had problems with drugs in the past. And some places represent to me things in terms of my mental and physical health, so you learn to move on, to preserve what your mission in life is, and my greater mission is my fans."

GaGa explained that she works "very hard", adding: "But when God opens that door for you - when life opens that door for you, I should say - I think it's important to be giving, to return the love back."

She also claimed that she has changed the way her fans "look at and devour" fame.

"It's something that tastes a little too sweet but is not so difficult to swallow," she said. "In the book of GaGa, fame is in your heart, fame is there to comfort you, to bring you self-confidence and worth whenever you need it.

"I want my fans to love themselves. It's almost like I want to hypnotise them so when they hear my music they love themselves instantly."
