This isn't the only time the star has opened up about their 1980s relationship. Earlier this year the singer confessed that Michael was responsible for so many of her life experiences.
"Let's just say I was 21 and my eyes were open to the world," the star told GQ Australia.
"I remember thinking that at the time, that of course his was the first funeral and the first kind of thing like that because Michael was just so many firsts in my life... He was. Yes, he was."
