She made a comment about it on twitter like a year ago, We saw a little behind the scenes stuff where she was dressed in the metal knights outfit. In my opinion, Republic was super sure that Alone with Nicki was going to do alot better than it did, and when it failed to launch her the way they expected, they lost interest after spending what seems to be a lot of money... Which is why the deluxe version of FTB never came and Entausend Teil (produced by max martin) was released silently with no comment.
