Lady Gaga says her father saved her from drug addiction.

The pop star - real name Stefani Germanotta - told US website ShockHound: "My father is a really powerful man, a telecom guy. So he looked at me one day and said, 'You're f***ing up, kid.' And I looked at him and thought, 'How does he know that I'm high right now?'

"And he never said a word about the drugs, not one word. But he said, 'I just wanna tell you that anyone you meet while you're like this, and any friend that you make in the future while you are with this thing, you will lose.' And we never talked about it again."

Gaga began regularly using the illegal substance after she dropped out of a music course at New York University in 2005.

The singer's friends also became worried about her erratic behaviour and begged her to leave her apartment and spend time with them.

She added: "My cocaine soundtrack was The Cure. I loved all their music, but I listened to this one song on repeat while I did bags and bags of cocaine.

"I didn't think there was anything wrong with me until my friends came over and said, 'Are you doing this alone?' 'Um, yes. Me and my mirror.'

"But I was able to stop, because I was panicking more on the drugs than I was sober. So I'm fine now."

The blonde singer still likes to party and confessed her record label often beg her to tone down her outrageous behaviour.

She explained: "I can drink, and I'm not going to say that I don't party. But it's not everyday, and it's no longer a tool for my creativity.

"The label gets mad at me for talking about it - they say, 'We don't want people to think that you're not a pop star.' But I am a pop star. I'm a pop star with a story!"
