Make mine a double

So, stars are sending body doubles to events now. I'm not sure what I find strangest about this article. Is it that:
a) A certain star (allegedly) actually used a body double - the sheer chutzpah, the cheekiness, the 'how on earth did they think up the idea in the first place'-ness of it all.
b) That she sent the double to do the bit I would have actually wanted to do, ie go to the museum, while sending herself off to do shopping, which I would gladly have sent a body double for. Imagine that - someone your height, weight and general shape, with same colourings and taste, who could go do jeans shopping for you for an entire gruelling Saturday! How exciting!
c) If it's not true, and she was just a bit off-colour and 'not her usual self' then who the heck made up such a loopy story to explain it?
d) How do you even go about hiring a body double?
And finally,
e) If you do have one, aren't you obliged, at least by the laws of fiction, to date the same guy in an amusing comedy of errors, or at least try to get your parents back together through a series of hilarious girlish high jinx adventures involving climbing up trees and spying through windows?
