Mumbai, March 23 -- Filmmaker Karan Johar was trolled by fans of his friend, actor Shah Rukh Khan, as Karan had 'liked' a tweet praising box office collections of Akshay Kumar's Kesari over SRK's Zero. The tweet said SRK's stardom was nothing compared to Akshay's. This made #ShameonKaranJohar trend online. Karan later clarified he was having a "technical problem" with his account, and would "NEVER" acknowledge such tweets....
