Singer Katy Perry says pop queen Madonna has inspired her "Part of Me" 3-D concert movie.
Perry invited a camera crew to film her California Dreams Tour and the documentary which will feature live footage of the gig and even touch on her personal issues, including her failed marriage to Russell Brand.
The singer admits, that plans for the forthcoming documentary were inspired by Madonna and her 1991 film "Madonna: Truth or Dare".
She added that Madonna is everything to her, and that the movie is amazing, because it caught Madonna at a time when Madonna was a bit more vulnerable.
She added that she wanted to do that too, to capture a snapshot of who she is now, so that she can remind herself what she’s lost, if she ever does become totally jaded.
