Actor Varun Dhawan, who was Alia Bhatt's co-star in the film 'Student of the Year', said he used to call her 'aloo' while they were shooting the film. "For a long time, I used to call [her] Aamir Khan because when she was around 20-21, her dressing sense was similar to Aamir. She would wear high-waist jeans," added Varun.
