Is it true Lily James is joining the cast? of is this another made up story like the, Maggie Smith, trying to get Rebecca Eaton fired, and the Simon Cowell joining the cast.

I was wondering that, myself. Since only one news outlet has reported it, I'm inclined to believe it's not true. A new cast member added to a toon as populair as Downton Abbey would, I think, generate a lot of news stories.
