Varun, Sidharth told me to not cast Alia in 'Student Of...': Karan

Karan Johar said that actors Varun Dhawan and Sidharth Malhotra had asked him to not cast Alia Bhatt in 'Student Of The Year'. "One of you said she is too young...I remember she stood quiet and didn't look at either of you...Either she was conscious or shy because you all already knew me...She didn't know me at all," he added.
