Ranbir Kapoor hit Katrina Kaif's nose so hard that she fell to the ground in pain.
The pair were filming Raj Kumar Santoshi’s forthcoming film Ajab Prem Ki Ghazab Kahani when the incident occurred.
Katrina was attended by a doctor and a nurse immediately and the film’s shooting was cancelled due to this incident.
A member of the film crew revealed: "An elaborate set was created at Madh Island and it was a chase sequence where Ranbir and Katrina were supposed to be running away from some goons. All was fine till the point where Ranbir needed to suddenly turn around. He did that but in the bargain hit Katrina’s nose with his hand and the delicate actress went tumbling to the ground. She was in great pain but realised that it was unintentional, so she didn’t complain."
Katrina confirmed the incident saying, "Yes (it did happen). It’s ok now."
