She tells Rolling Stone magazine, "Being myself in public was very difficult. I was being poked and probed and people would actually touch me and touch my clothes and be like, 'What the (hell) is that?' Just so awful.
"It was like I was being bullied by music lovers, because they couldn't possibly believe that I was genuine."
However, after three years in the public eye, Gaga has learned to love her fame - and admits she would be lost without her fans.
She adds, "We have this umbilical cord that I don't want to cut, ever. I don't feel that they suck me dry. It would be so mean, wouldn't it, to say, 'For the next month, I'm going to cut myself off from my fans so I can be a person.' What does that mean? They are part of my person, they are so much of my person. They're at least 50 per cent, if not more."
