Karan Johar secretly shoots a song for Ae Dil Hain Mushkil 

Karan Johar is maintaining caution with the looks of his characters in Ae Dil Hain Mushkil. The last few portions of the film remain to be shot. ADHM will be a huge Diwali release and is touted to be an intense romantic drama. 

Recently, KJO insisted his cast and crew to report at 3 AM to shoot a song, in order to ward off the paparazzi. A source added, "Karan shot a major chunk of the film in London, and has revealed little about the actors' look and their characters. He has been posting only generic pictures from the set on social media. Recently, when he shot a song with Ranbir and Anushka at Mehboob Studios, he called for extra security. 

"He felt the paparazzi might end up clicking the actors' pictures and their look would be leaked. So, he chose to do it during odd hours, when there was less risk. He called the actors and crew at 3am. The shoot was completed without a hitch and the media didn't get a whiff of it."

The film will be a love triangle among Ranbir, Anushka and Aishwariya with Saif and Fawad Khan in cameo roles.
