/> Strangely for an intense love story there's a abysmal lack of sexual synergy between the lead pair in Love Story 2050.

And that's because Priyanka point-blank refused to kiss Harman at a crucial juncture in the plot....or perhaps 'point-blank' isn't the correct term to describe Priyanka's reasonable decision to not smooch on screen, even if the co-star happens to be her real-life boy-friend.

When asked about the kiss that the Ms gave a miss Harman laughed, "How did you get to know about?

It's true both Dad and I felt a kiss would have been most appropriate midway through the narration when the first Priyanka character dies in my arms. Dad had written a kiss into the story here.

I was supposed to kiss her as she dies in my arms. But Priyanka chose not to shoot the kiss. We respected her decision and let it be."

But what's with Priyanka's reluctance to express love in a natural way, with a kiss specially when the co-star is Harman?

"That's exactly why she didn't do the kiss, " explains Harman. "She couldn't make a concession with me because then other filmmakers would've accused her of preferential treatment. So we simply scrapped the smooch."

Priyanka incidentally, had done a kiss in her first film Andaaz.

"But that's when she was new and had no choice. Now on principle she won't kiss on screen. I respect her decision," defends Harman.

Priyanka is pretty clear on the issue. "It doesn't matter who the co-star. I won't do certain things on screen. Period."
