Shahid told IANS: “This is so insulting. I am ashamed of Karan Johar. I didn’t expect this from him at all. My dad has sung songs for Karan’s father (Yash Johar) and this is what he has done now. I haven’t seen the film yet.

Talking about his father’s fans, he said: “It’s been 36 years and still his fan following is only increasing day by day. People tend to forget singers in just a few days but look at my father’s body of work and his fan followers.
