There's something about real-life couples coming together on the Bollywood screen.

Their films don't seem to be working at all at the box office. This seems to have become the golden rule these days. In the year 2009, Kurbaan being the latest example of a real-life pair's film failing at the ticket windows.

Explains a trade source, "It is probably, with so much of media boom, the audience gets more than its dose of the real-life star-couple's antics because of which there may be no charm left for them to see the same pair on screen.

But then this was not the case in the good old days when stars were very discreet about their affairs and would not go about flaunting them.

Also, media was not half as intrusive then. Whatever the reason, it seems risky to cast love birds in the same film today.

More so, after Salman Khan and Katrina Kaif's Yuvvraaj tanked at the turnstiles. Much like Kareena Kapoor and Shahid Kapoor's Fida bombed at the box-office. Their Jab We Met clicked but it was released only after the two had split."
