I'd love to know to. But my guess is that it was another one of her crazy spurts, where she advertises b/g, then removes any trace of it. Like the twitter pics, for instance. And the 3-4 times before that that she's done very similar things. I really don't understand what her problem is. Most people that would be interested in seeing b/g of her have already seen the 2 videos that got out, so it's not like it'd ruin her "career" or anything. In fact, I'd say the only thing that would really save it would be if she actually committed to it.
She's gotten a reputation of being a greedy liar with her teases and lies about doing b/g videos. And I think most people are sick enough of that, that they don't want to just settle for more of the same old videos.
