Where on one hand the media try to get the latest scoop about the arch rivals, the two seem to be having a very cordial relation and keeping in touch with each other on a regular basis. Also one reason behind their friendship can be Rajkumar Hirani who has maintained a good kinship with both the stars. Also King khan had revealed in a daily interview had he was the first Indian to see PK's poster.
Post release of PK's poster when the Aamir was accused of obscenity and cheap promotion tricks, to which SRK as a loyal friend stood up and supported Aamir by saying that there was a relevance of nudity in the poster which one could discover later.
No one can say what is cooking between the two actors whether its friendship or war but one think is sure that King Khan's got Aamir's back!
