Deepika Padukone's publicity machinery had worked overtime when there was talk of her doing Fast & Furious 7 with Vin Diesel. However, that went kaput. Now, from the time Deepika posted a picture of herself with some one who closely resembles Diesel from the back with the symbol of his film, XXX, in the backdrop online and tagging the Hollywood action star, everyone has begun speculating whether she is in his next film. No one from her side was available for comment.
