I was reading this article, and it says that Sony has offered to let her work with another producer.

She apparently feared that they would not promote her album, but if the album was good, even without Luke they might promote it. And even if they don't, it's not as if she can't promote it herself. Maybe I'm completely off here, but I just don't understand why she doesn't just work with another producer?
She's not forced to work with Luke, and she can make music still.
