Earlier it was reported that SRK was just to play a cameo in the film ‘Student of the Year’, being directed by KJo who is launching Mahesh Bhatt’s daughter Aalia along with David Dhawan’s son Varun.

However, Karan ramped up old friend Khan’s performance from a cameo to a much bigger role, most likely of a professor.

Speaking to a daily, a source said, “Rumours about SRK acting in KJo`s next had been doing the rounds but Karan`s constant silence about the film started giving people the impression that SRK was only planning to produce the film.”
