While her upcoming 3D documentary ‘Part of Me’ promises to showcase much of Katy Perry‘s life on tour, backstage and everywhere in between, there are a few things that won’t be covered: Her relationship, marriage and split with Russell Brand.
Yet another promo has been released by HBO for their upcoming Lady Gaga documentary. In this excerpt, she’s shown hanging out in a car with some friends, and says that she always knew that she was “gonna make it” as a musician. She’s also seen walking down a New York City street not wearing much besides high heels, a jacket and a thong. See the new clip now on after the jump.
