Speaking to WWD, GaGa said that she tries to follow the path that her father's sister Joanne Germanotta may have experienced if she had not died aged 19, as a result of the immune condition lupus.
GaGa explained: "I really believe I have two hearts. I think I actually carry two souls in my body, and that I'm living out the rest of her life and her goodness - she died a virgin, she died never having experienced all these things that we all get to love and experience in our lives.
"I think that I work in her image. I work in this life as part pop singer and part humanitarian, and to do great things for people because she was a good person and I don't think she had enough time to do enough good."
