Could this be a look from Yash Chopra's film, for which he is currently shooting, we wondered.
So we phoned Yash Raj Films and this is what the spokesperson said: "SRK has two looks in the film. It's not a double role. We can't divulge any more information." Meanwhile, Queenie Singh says: "Shah Rukh was shooting for his movie and dropped by before the event. I clicked the picture while he was there. He hasn't put on weight, it's the light above and his jacket which made him look different."
