Actress Deepika Padukone has been addressing the veteran actor Amitabh Bachchan as Baba for a while now and the two share a tender father-daughter like relationship. The two actors are currently shooting for Shoojit Sircar's upcoming film 'Piku' in which Big B play the role of Deepika's father.
The other cast and crew of the film also started addressing Big B as Baba which is very sweet and respectful. Sr. Bachchan wanted to reciprocate the loving gesture and hence gave a nick name to the beautiful actress and started calling her 'Deepiku'. The forthcoming film 'Piku' is shot in Kolkata and the two actors will essay Bengali characters in the movie.
