Mani Ratnam's next with Aishwarya Rai?

If the grapevine is anything to go by, Mani Ratnam's next will be a Hindi-Tamil bilingual. Also, there are rumours that he has approached Aishwarya Rai for the film, and after the two were in talks for years, it looks like things could materialize soon. Meanwhile, recent developments suggest that Aditi Rao Hydari could be a part of it. However, nothing has been made official. In an interview with CE during the release of Kaatru Veliyidai, Aditi had said she'd "love to work with Mani Ratnam again as he's a magician, who creates sheer magic on screen."
