The My Name is Khan helmer's company Dharma will start shooting next year with the Golmaal filmmaker.
Johar told the Mumbai Mirror: "Dharma Productions and Rohit Shetty will come together. All of us in the company are really excited about this association.
"Rohit is an extremely talented mainstream filmmaker and I am sure, together, we will make a very special film."
Shetty also told the publication: "I have immense respect for Karan's father. He is an excellent director himself and a director's producer.
"We have met and finalised that we would be doing a film soon. We will decide the set up and other details very soon. I am sure it will be a great experience."
It was reported this week that Johar will bring Shah Rukh Khan and Kajol together again on screen next year.
