It seems that the gorgeous onscreen couple of Hrithik Roshan and Katrina Kaif has given their heart and soul to their upcoming film 'Bang Bang'.

The trailer of the film took people's breath away and the songs which are being released one by one are climbing the popularity charts fast.

After the super success of the dance number 'Tu Meri', a soft romantic song 'Meherbaani' has been released by the makers of the film. Though it's the job of the actors to promote the features of their films, both Hrithik and Katrina have fond memories of this song.

Hrithik claims that the song is stuck in his head. "This is a romantic track that I haven't stopped humming since I heard it. Hope everyone loves this song as much as I do," he said while Katrina states that shooting for the song in Greece made it a magical experience for her.

"I think Ahmed (Khan, the choreographer) captures modern love songs well, making it seem effortless and new. Add to that Sid and Ahmed's camaraderie, stunning locations and styling by Anaita Adajania Shroff. It's the first time I'd been to Greece and it was breathtaking. With all that support, Hrithik and my job was easy," she said.

As Kat compliments Siddharth, the director himself adds that this song is a key turn in the plot as it signifies how the characters realise about their love. "There are love songs and then there is Meherbaan. This is the first song we made for Bang Bang and it has got three superstars — Hrithik, Katrina and Greece," he added. 

An official remake of Hollywood hit 'Knight and Day', 'Bang Bang', produced by Fox Star Studios, releases on October 2.
