The trailer of famous Bollywood producer-director Karan Johar`s popular chat show “Koffee with Karan 7” was released on 2nd July evening. The show will air on Disney+Hotstar. The trailer, as expected, is full of fun conversations, candid chats. One moment, however, that eclipsed everything else in the trailer has to be this hilarious input from Samantha Ruth Prabhu. In a segment of the trailer, The `Family Man 2` star tells show`s host Karan Johar: “You are the reason for unhappy marriages. You have portrayed life to be K3G (Kabhi Khushi Kabhie Gham). In fact, the reality is KGF.”
