Lady Gaga and HBO have released another promo for her upcoming documentary.  In this one she's hanging out with some friends in the car and says that she's always known that she was going be a star and a musician.

As usual Gaga's dressed scantily and walking down a New York City street.  Catch the promo after the jump.

The documentary is set to air on HBO on Saturday, May 7th -- do you plan on watching this?
