Asked what does he have to say about Salman and Katrina Kaif's chemistry in the film, Shah Rukh said: "It is very nice they have done few movies together. I think chemistry is a too deeper word... media has created it. Kajol and I always had this issue, 'what is this chemistry?' It has taken me years to understand what this means."
However, Shah Rukh added that Salman-Katrina look wonderful together and even wished them luck for their film.
"I don't know about the chemistry but it looks like a wonderful pair. I wish them all the luck," he said during an event.
After Salman, Katrina will be seen with Shah Rukh in an untitled project directed by Yash Chopra. The film also features Anushka Sharma.
