According to sources, the shoot was on in South Africa. There was a scene where Diya introduces Irrfan to Fardeen Khan, and Irrfan comes forward to kiss Diya on the cheek and make it clear to Fardeen to not enter into his territory. He has to do this because he suspects something is going on between Fardeen and Diya.
However, everyone was surprised when Irrfan suddenly kissed Diya on the lips. It was unexpected, not being a part of the script, but she chose not to make an issue about it at that time and simply called up Sanjay later on.
Meanwhile, Diya doesn"t seem to be very upset. She admits she was surprised, but she thinks that he did it to establish the chemistry between them in the scene. She also thinks it wasn"t much of a kiss. Sanjay also feels that Irrfan did it to make the scene look more real. After watching the rushes, he feels Irrfan succeeded. And since Diya isn"t making an issue over it, he"s fine with it too.
