Saif Ali Khan and Sharmila Tagore, the mother-son duo, made an appearance together on the latest episode of ‘Koffee With Karan 8’. The episode was quite interesting as the two made several revelations, including the fact that Sharmila Tagore was diagnosed with cancer, and hence, she had to reject Karan Johar’s offer to star in ‘Rocky Aur Rani Kii Prem Kahaani’, which was helmed by Karan, and starred Alia Bhatt and Ranveer Singh in the lead roles.
