SRK's Song For Katrina, Most Romantic Song ByYas.C

Famously, it was poet-thinker Harindanath Chattopadhyay who said, "It's very difficult to be simple". By his reckoning, Katrina Kaif's most difficult role is in 'Jab Tak Hai Jaan'.

While for Katrina's previous film 'Ek Tha Tiger', director Kabir Khan had insisted that she wear clothes from her own wardrobe which Katrina has happily done.

As a friend of the actress says, "Casual wear is Katrina's biggest joy in life. She hates to dress up and put on makeup. She is happiest when unadorned. No wonder we see her face plastered with a smile during the 'Ek Tha Tiger' schedules."

Interestingly it's just the opposite for Katrina in 'Jab Tak Hai Jaan' where she is throughout dressed up to look urbane cool.

Says a source close to Katrina, "For JTHJ, Katrina was given a far more chic appearance. Even when she is doing a casual song in the park the 'casual' look has been considerably worked upon."

Apparently Yash Chopra is adamant on transforming Katrina into the archetypal Yash Chopra heroine.

In fact the poet par excellence Gulzar has penned a paean to Katrina's beauty that A R Rahman has composed for Shah Rukh Khan's character to sing.

Says our source, "It's Gulzar Saab's most romantic song since Jab bhi yeh dil udaas hota hai jaane kaun aas-paas hota hai. And it can't be sung to Katrina in torn jeans and floppy top."

Apparently Yashji has been telling friends the love song that Shah Rukh sings to Katrina is the most romantic number he has shot since Kabhi kabhi mere dil mein.

As a source close to both the projects put it, "The difference between Katrina's look in Ek Tha Tiger and Yashji's film is the difference between the girl next door and the girl next door to the most romantic guy. She is real-life normal in Kabir Khan's film and a glamorized avatar of normal in Yashji's film."
