Saif Ali Khan is currently shooting for his upcoming film, 'Happy Ending', in US. Directed by Raj Nidimoru, this romantic flick has a lot of bonding on and off-screen too! As we know, lovely co-actress Kalki is the new addition and shares the screen space with this bollywood nawab, in the film, the two are seen quite at ease, when together.

Reportedly, Saif and Kalki have bent down to sharing the same personal interest of reading! Since Saif loves reading, and also has a huge library at home, the actor even recommended Kalki some books. Kalki, being a bibliophile, loves to read. Apparently, when Saif suggested her a few books of his choice, she ordered them right away.

Now, one would wonder if Kareena would get bothered at the new-born friendship but well well well! All goes well with this nawab couple! Allegedly, Kareena Kapoor herself is bonding with Kalki Koechlin. Though Kareena is not that into books, the duo shares a common interest in music!
