Reportedly, Saif Ali Khan was in a bad mood during the shooting of Humshakals promotions on DID Lil Masters, since the air conditioning on the sets had some issue and so he refused to come out of his vanity van since he could not take the excessive heat.
"It was too hot on the sets as their air-conditioner wasn't working. Saif just wanted to wait for some more time in his vanity van. Besides, he was wearing a suit, so I don't blame him." said Sajid.
That is not all, there is another version of the story which says that, just when Saif got out of his van to enter the sets, someone exclaimed saying, "Wow, Nawab aa gaya," (the prince has come) and Said went right back into his van hearing this. Following this Sajid Khan had to cajol him to finish the shoot.
When asked Saif to shed some clarity, he said, ""Why would I get upset if someone called me a Nawab? I just went to the van because it was too hot outside."
