Lady Gaga recently revealed to Observer Music Monthly that back in the day she used to have a pretty bad cocaine addiction.She used to sit at home and snort "bags and bags of cocaine" by herself while listening to The Cure."My cocaine soundtrack was The Cure. I loved all their music, but listened to this one song on repeat while I did bags and bags of cocaine. 'Whatever I do/It's not enough.' Isn't that funny.""At the time 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."Thank God Gaga's dad stepped in and knocked some sense into her and got her to quit."My father is a really powerful man, a telecom guy. So he looked at me one day and said, "You're f***in' up, kid." And I looked at him and thought, "How does he know that I'm high right now?"Gaga also admits that she isn't too keen on her fellow celebrities."I prefer non-famous people who have The Fame. I myself don't like celebrities. It's the idea that you can be whoever you want to be. You don't have to be a victim of your environment. You can become the image of yourself you project, [that] you could become in the future.""I just haven't had an excellent personal experience with celebrities. But I'm sure there are a few lovely ones. I have made a few friends, of course."
