Ranbir Kapoor is all set to appear opposite the beautiful Katrina Kaif in the upcoming Ajab Prem Ki Ghazab Kahani.

During the shooting of the movie, the lead pair had lots of fun teasing each other.

According to a birdie, 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”.
