"Let's just say I was 21 and my eyes were open to the world," the star told GQ Australia."You want to experience everything and I couldn't think of a better person to, you know, take those first steps into the big wide world with."
"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."
