Ranbir Kapoor who will be next seen with beautiful Katrina Kaif in the forthcoming movie Ajab Prem Ki Ghazab Kahani has given her a nickname.
A birdie informs that Katrina and Ranbir were required to climb a ladder which was 200 feet high. And Katrina climbed it, comfortably leaving Ranbir behind.
Everyone was quite surprised with delicate Katrina's daring act. Since then Ranbir addresses her as Rambo's sister "Sambo".
