The 'Born This Way' hitmaker explained the self-titled visual dialogue ' which will feature 350 black and white pictures taken of the singer by American fashion photographer Terry Richardson over a 10-month period ' will be "completely unfiltered" and even feature intimate moments in the bathroom.
She told MTV News: "Terry was with me for [almost] a whole year, and, gosh, I didn't hold anything back from Terry ... he was with me every minute, every moment.
"It's completely unfiltered. He has photographs of me waking up in the morning, brushing my teeth, in the bathroom, in the bathtub, the shower. And the thing about Terry, if you know anything about his photography, is that nothing is staged; I mean, that's sort of what he is renowned for. He can get you to do things and he can capture things that no one can ever capture."
Gaga ' who has been captured in more than 100,000 images by Terry - said the forthcoming project, which will be released on November 22 and feature an introduction written by the singer, includes "ridiculous" pictures, such as her urinating in a cup.
She added: "My favourite thing, honestly, is that [Terry] loved the fans. He shot the fans the same way he shot me: with no pretence. No 'Well, she's put out records and they haven't.' None of that. The music was all of ours.
"He would come backstage and he would say, 'Oh my God, the fans!' And I'd say, 'I know ... I know what you just photographed.' And he'd say, 'Baby, wow!' And then he'd film me, like, peeing in a cup and, like, ridiculous things."
