I'm pretty sure she didn't. she has an instagram account that is private, and only friends of her are supposed to be following it. apparently, some of her friends are not that friendly and spill her pics all over the net.
(i don't know of this particular picture, but almost every recent pic we have has leaked in some way or the other. i can't believe she seems to trust in the privacy of her instagram account...)
