Katy Perry - Madonna Inspired Perry Concert Film
Katy Perry has credited pop queen Madonna with inspiring her upcoming 3D concert movie.
Perry invited a camera crew to film her California Dreams Tour for Part Of Me, which will feature live footage and touch on personal issues including her failed marriage to Russell Brand.
The singer admits plans for the forthcoming documentary were inspired by the Material Girl and her 1991 film Madonna: Truth or Dare, which chronicled the pop icon's Blond Ambition World Tour.
She tells Teen Vogue, "Madonna is everything to me, and that movie is amazing, because it caught her at a time when she was a bit more vulnerable.
"I wanted to do that too, to capture a snapshot of who I am now so that I can remind myself what I've lost if I ever do become totally jaded."
Part Of Me is due in theatres in July (12).
