Ranbir Kapoor 'learned to milk cows for Rockstar role'

Ranbir Kapoor has reportedly learnt to milk cows in preparation for his role in Rockstar.

The actor plays a son in a rural Jatt family whose ambitions to become a famous musician tragically come true.

A source told Hindustan Times: "[Director] Imtiaz Ali and Ranbir spent an entire day with a Jatt family based in the outskirts of Delhi. They would hang around with the young boys of the family, sleep on the cots, eat out at local dhabas and enjoy hookah in the evening.

"Ranbir had the time of his life trying to milk the cows. It was such an amusing sight, everyone was in splits.

"But all in all, they learnt a lot about the lifestyle of a typical Jatt family, which was important for filming; and also ended up having a great time doing things that they wouldn't otherwise get to experience."

In April, Kapoor was rumoured to have been depressed after filming very emotional scenes for the film.
