Deepika Padukone has been addressing Amitabh Bachchan as Baba (father) for a while now. The two actors are currently shooting for Shoojit Sircar’s upcoming film, Piku, in which Big B and Deepika play father and daughter respectively.
Apparently, not only Deepika, but also the other members of the cast and crew of the film, including Irrfan Khan, call him Baba now. "Bachchan sir likes the way Deepika and the others address him as Baba," says a source from the film’s unit.
So, to reciprocate the gesture, Big B has coined a nickname for Deepika too. "He calls her Deepiku, nobody else addresses her by that name," adds the source.
"The way they address each other, on and off the sets, shows the comfortable relationship they share," says Juhi Chaturvedi, the writer of the film, which has been shot in Kolkata and will see Bachchan and Deepika play Bengali characters.
