Star son and star actor Ranbir Kapoor has given his foreword for the autobiography of his father Rishi Kapoor. Rishi Kapoor's autobiography is titled 'Khullam Khulla: Rishi Kapoor Uncensored' and the title of book itself suggests many untold stories about the star's life.

Neetu, Rishi Kapoor's wife revealed one non-negotiable rule that Rishi follows - each family member has to message him 'Jai Mata Di' when taking off and landing anywhere!

Neetu says, "Once Ranbir messaged him after boarding a flight but there was a delay in the actual take-off. Meanwhile, Bob had mentally calculated the time of arrival based on when the message had been sent, and when he didn't hear from Ranbir at the estimated time, he went berserk. Eventually, when Ranbir did land, he got his ear chewed off. His father's point was, 'Why did you message me when it wasn't yet time for take-off? I timed your landing in my head and I was worried sick.'"

Neetu explained an another incident, "During the promotion of Besharam, when all three of us flew together, Ranbir said much to my amusement, 'Thank God both you are there. Now I don't have to message and say 'Jai Mata Di.' It's such pressure on me that if I slip up, Papa will go mad."
