"I am little unwell... Having fever. I travel so much... Then shooting, so getting less sleep. I am not tired but I am unwell. I get irritated when people show they are unwell," Shah Rukh said.
He attended the 'Lux Chennai Express contest', a campaign where people get a chance to go on a romantic train ride with him.
A short-listed participant got an opportunity to enact the legendary train scene from 'Chennai Express' with the actor who broke into an impromptu jig with the 20 other participants.
He recalled how shy he felt when shooting for one of the advertisements of Lux where he was surrounded by actresses Juhi Chawla, Hema Malini, Sridevi, Kareena Kapoor while he was in a bath tub.
