Aditya's liplock with Katrina in 'Fitoor' his longest on-screen kiss!

Aditya Roy Kapur, Katrina Kaif

Aditya Roy Kapur's liplock with Katrina Kaif in 'Fitoor' is set to be his longest on-screen kiss.

The actor has smooched in his earlier films - 'Aashiqui 2', 'Yeh Jawani Hai Deewani' (both 2013) and 'Dawat-e-Ishq' (2014), but for short fleeting moments.

Perhaps it has something to do with the chemistry he shares with Kat in the film.

Aditya's next is 'OK Jaanu', a remake of the Tamil flick 'OK Kanmani', with rumoured ladylove Shraddha.

It's a love story, so another kissathon is on the anvil.
