Ranbir Kapoor is all set to begin working on the most talked about Sanjay Dutt biopic. The actor is prepping up himself to get into the skin of the character. Ranbir is beefing up to resemble a body like the Munna Bhai MBBS actor. He has gained as much as 13 kgs of muscle weight to look like young Sanju baba. The Jagga Jasoos actor is following a special diet and fitness regime to get a good waistline reduction. Ranbir’s fitness trainer, Kunal Gir says, “Ranbir has an hour-and-a-half of intense work out sessions per day. Its a big challenge to bulk him up but he’s committed to do whatever needs to be done. He wakes up at 3 am, has a protein shake and goes back to sleep.” While Ranbir is in all work mode, we get to know that Sanjay Dutt was desperately wanting to bash his father Rishi Kapoor.

Yes, you got that right, Rishi Kapoor was once at Sanju Baba’s hit list and the PK actor wanted to beat him up. Recently, Rishi Kapoor’s biography Khullam Khulla was released and since then it has been news for making shocking revelations. In one such revelation, the veteran actor said that once Sanjay Dutt and Gulshan Grover had turned up at his door to beat him up. Recently, in an interview with, Gulshan Grover decided to elaborate on the incident. (ALSO READ: Did Kaabil producer Rakesh Roshan make a rude remark on Rishi Kapoor’s career?)

Sanju baba didn’t like the fact that and decided to beat up Rishi for eyeing his lady love. The Vaastav actor took Gulshan Grover along and arrived at Rishi Kapoor’s residence. However, they met Neetu Kapoor at the door, who was not married to Rishi at that time. (ALSO READ: Jagga Jasoos: Ranbir Kapoor & Katrina Kaif finally bond on sets; all thanks to Anurag Basu)
