Abhishek explained: "He is aware that people get gobsmacked in front of him, so he goes out of his way to make them feel comfortable. He does it for the sake of the film. Also when he is shooting a song, he likes to have a lot of fun."
The father-son Bollywood stars have recently completed a song for new film Bol Bachchan.
"It is weird, but dad is the one co-star with whom I have done the maximum work," said Abhishek.
"We've done Bunty Aur Babli, Sarkar, Kabhie Alvida Na Kehna, Sarkar Raj, Paa, Buddha Hoga Tera Baap, Jhoom Barabar Jhoom and now this song in BB."
The second-generation star added that he still has a long way to go to be as good an actor as his father.
Speaking about his current role, he revealed: "I'd give my final performance a five. I'm very harsh with myself."
