Of late a pic of Ranbir Kapoor with Karan Johar went viral, where the actor is seen in intense look while the filmmaker wears a smile. Everyone went gaga over this pic, which was taken in London during the shooting of KJo's film 'Ae Dil Hai Mushkil'. However, Karan's buddy Shah Rukh Khan was amused with this photo.

Besides appreciating the fact that the pic looks nice, SRK was pulling Karan's leg by saying that although he looked good in front of the camera, his actual work lies behind it. "@karanjohar looking good bro & as much as it pains u but alas! sum time tonite u will have to get behind the camera & do ur job..", tweeted the King Khan.

'Ae Dil Hai Mushkil' also stars Anushka Sharma and Aishwarya Rai Bachchan in lead. While Anushka has joined the team in London, Aishwarya is expected to start shooting any time soon.
