Apparently, the two actors found themselves on the same flight, and bonded well! We hear they requested that they be seated next to each other and jabbered away till the flight landed.
Since the two realised that they got along pretty well, they spoke about working together sometime! Apparently, Ranbir and Shahid are both good dancers and may seen making a world tour together.
When we quizzed Shahid about it, he said, "Yes, it's true! We may participate in a world tour. Nothing is official, nothing is on paper. We've just mentioned it to each other. Of course, there'll be a lot of logistics to sort out, like our dates and the places where we are shooting. But I'd love to be a part of Ranbir's worl tour."
Shahid who turns a year older soon says that his birthday wish is just 'happiness and more movies among other things!'
