Another Promo For Lady Gaga HBO Doc

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.
