Lady Gaga's Paparazzi Video

Quick authorship question. When I am watching this video, whose visual ideas am I watching? How much of it is not just signed off on by her herself, but actually “thought up” by her so to speak?

I am always curious about this with pretty much every music video I ever see, but anyway, the one that passed across my facebook feed this morning was this particular video (someone was pointing out an example of how they hate long intros to music videos) so, I ask about this one today.

Basically I’m curious as to whether I’m looking more at the work of a single artist aided by craftspeople and technicians, or instead a collaboration between multiple artists.
