NEW DELHI: Filmmaker Karan Johar who recently made a lot revelations about his personal as well as professional life in his autobiography "An Unsuitable Boy," has opened up on his rift with best friend Kajol.

The 44-year-old director gave out further details saying that actress' husband Ajay Devgn said "nasty" things to him before the "Ae Dil Hai Mushkil" and "Shivaay" box office clash.

"Ajay Devgn called me and shouted at me and said some really nasty things because he heard at a party that I'd said some things about his wife. She was one of my closest relationships, as close as family could get, but it got unpleasant," said the ace filmmaker.

 The ‘Ae Dil Hai Mushil’ director who considered Kajol as her lucky mascot has made many confessions in his autobiography.

"Ajay said I'd bribed a trade analyst to write bad things about his film and praise mine, then he put out a statement saying there should be an investigation and she retweeted it saying 'SHOCKING'. And that was it... I don't want to say anything more, but yes one thing I'd like to say & I stand by it is that this is not a phase, a feeling that will change. No matter what, she's out of my life," said the 'Ae Dil Hai Mushkil' director.

Karan Johar and Ajay Devgn's ugly spat came into public domain when the actor shared a recording of self-proclaimed critic Kamaal Rashid Khan saying that Karan bribed him to write good review about ADHM and criticise 'Shivaay'.
