When Ranbir punched Katrina

Recently while shooting for Ajab Prem Ki Ghazab Ki Kahani, Ranbir Kapoor accidentally punched Katrina Kaif on her nose.
They were shooting for a scene where Ranbir is trying to save Katrina from bad eve-teasers, and then accidentally punched Katrina nose, however Katrina took it in good humor.

A source says, “Ranbir, are you trying to save me from the goons or are you saving the goons from me.”

Now that’s quite humorous side of Katrina.
