Few days back there was a news that Tiger Shroff has been offered the sequel of Karan Johar's "Student of the year" and he is going to do that film. Karan Johar has said to his team to keep Tiger in mind. But now the story is twisted. Actually, Dharma Production recently auditioned Shahid kapoor's brother Ishaan Khattar for this film. Ishaan is preparing from many days to enter in Bollywood and Shahid is helping him a lot. Ishaan Khattar is son of Rajest Khattar and is working as assistant director in Udta Punjab. So one thing is clear that casting of Student of the year 2 has been started, so script is also ready. Karan Johar has decided to make his superhit film in series, so he has started his preparation.
