Juno Temple Playing Female Robin?

Yesterday I reported that Juno Temple is up for the role of a street wise girl in the third "Batman" film. Now it seems that role has changed and the role is now gonna be the role of the female Robin, Stephanie Brown.
Nolan did say, before production on the film began, that Robin will not appear in any shape or form. Maybe he's changed his mind. So is Juno Temple playing the female Robin in "The Dark Knight Rises"?
