The eccentric singer revealed her father's sister Joanne Germanotta died from the immune condition lupus when she was 19, and said she tries to have experiences her aunt would have enjoyed.
She told WWD: '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.'
