Saif has always showed his love for books and Kalki is also known to be a bibliophile. So while they were shooting for the movie together, they found a common interest in Books and have never stopped talking about it since then. Word is that Saif has recommended a few books to Kalki from his huge library and Kalki went on to order them immediately.
Now before you think Kareena Kapoor should be worrying about this new friendship between the two co-stars, let me tell you that Bebo has a good rapport with Kalki as well. Kareena apparently, loves European music while Kalki being French, enjoys it too.
Saif Ali Khan is the producer of Happy Ending which is being directed by Raj Nidimoru and Krishna DK. The movie also features Ileana D’Cruz apart from Saif and Kalki and is expected to hit the screens early next year.
