They also talked about authenticity, and Gaga said she didn't want the documentary to come off as "a big commercial" for her or to paint her as perfect.
Part of that authenticity was choosing to include her personal struggle with chronic pain in the documentary.
When asked about it during the press conference, Gaga became visibly upset at first, and held back tears before simply saying, "It's hard, but it's liberating, too."
"There is an element and a very strong piece of me that believes pain is a microphone," Gaga added. "My pain does me no good unless I transform it into something that is. So I hope people watching it who do struggle with chronic pain know that they're not alone."

"There is an element and a very strong piece of me that believes pain is a microphone. My pain does me no good unless I transform it into something that is. So I hope people watching it who do struggle with chronic pain know that they're not alone. It's freeing for me ... and I want people that struggle with it to hear me. There is a degree of self-deprecation and shame with feeling in pain a lot. And I want people that watch it — that think there's no way I live [with chronic pain] because they see me dance and sing and don't think that could possibly be — to know I struggle with things like them. I work through it and it can be done. We have to stick together. I don't have to hide it because I'm afraid it's weak. It's a part of me, and I'm grateful to Chris for caring. The compassion is overwhelming. That's why it makes me emotional. It's very touching.
