Khullam khulla pyaar karenge, hum dono!

Remember Rishi Kapoor and Neetu Singh's infectious declaration of romance in Khel Khel Mein?

On screen, movie stars are unabashed about indulging in a physical show to demonstrate fondness. Off screen, however, it's an altogether different story, especially with the paparazzi keeping a close eye on their each and every move.

Still, not all movie stars are conscious of rendering hugs and kisses to their companions or co-stars in the presence of cameras.  

And so from Tom Cruise to Shah Rukh Khan, here's a look at some of celebrities indulging in PDA (public display of affection).

Tom Cruise and Katie Holmes

Jumping on Oprah's couch, popping the question at Eiffel Tower, smooching on the red carpet, followed by a fairy tale wedding in Italy, Tom Cruise re-defined besotted, leading to much criticism among fans and media. That's the Katie Holmes effect for you. And from the looks of it, there's no stopping this golden duo of Hollywood.

What happens when the sexiest man and woman of Hollywood come together? They make never-ending headlines.

Brad Pitt and Angelina Jolie remind us what makes them so written about by getting up, close and personal in the middle of a red carpet event of a movie premiere.
