If one goes by the book, love is always in the air -- on the sets, throughout a movie and even in reality shows. 2013 too had a varying dose of that particular emotion thanks to some who were unabashed in their public display of affection as well as those who simply won’t come out to declare their love for each other. Whichever route the filmy stars chose, love is definitely in the air. And HitList rounds up a few of the couples who piqued our interest with their undeniable intimacy...

Ranbir Kapoor and Katrina Kaif

The two are clearly in love. But they won’t talk about it. Fair enough. At the same time, they can’t keep us from doing our job. If last year was rife with speculations, this year was full of evidence (yes, photographic too) and only blindness can refute their romance. In all probability, the two are bound to grow stronger in the coming months and whether they like it or not, we’ll be keen to know more as always.
