The level of secrecy can be understood by this fact that even Neetu’s superstar son Ranbir Kapoor doesn’t have a clue of it.
Neetu Singh along with son Ranbir made an appearance on the show to promote their upcoming movie 'Besharam'.
As soon as Neetu entered the stage Big B greeted her with a secret gesture by waving her hands. Ranbir who was standing beside his mother couldn’t understand the secret signs and questioned Big B about it.
Bachchan revealed that this was the way they greet each other every time they meet and he cannot reveal anything else. All he said that this was something that happened in Rome when they were shooting 'Great Gambler'.
