The delicate darling Katrina Kaif took everyone by surprise by displaying her tough side while shooting for an action sequence in her forthcoming venture Ajab Prem Ki Ghazab Kahani.
It is believed that Katrina and Ranbir were required to climb ladder which was at a height of 200 feet while Ranbir was to save Katrina from goons and then escape on a jet ski.

A close hand reveals, “Everyone on sets was quite skeptical about Katrina. However, Katrina amazed everyone as she comfortably climbed the ladder leaving Ranbir lag behind.”
Ever since that day Katrina has always been addressed as Rambo’s sister Sambo by Ranbir.
