Deepika Padukone shot for her Hollywood debut film, XXX: Return of Xander Cage, along with Vin Diesel for about three months in the US. And looks like over this period time she has developed a deep bond of friendship with her co-stars, including Vin. Throughout the time when Deepika was shooting in the US, we had seen her posting fun pictures of her with her co-stars from the film. And now, today being Vin Diesel's birthday, Deepika shared an old picture of both of them from the film's shooting with a cutesy message.
