good friends off screen

guys we watch bhola, anya , raghu, eshaa on the screen.from the chemistry that we watch among them,which pair do u think get along well as friends off the screen.like they r working together for about nearly 1 yr for 12-13 hrs every day so obviusly there must be some bonding b/w them. so what u guys think? i think it is priya & sudeep.bcoz they r the leads . they have most of the scenes together.
