Shah Rukh introduced AbRam to Kolkata when the star father was in the city earlier this month to cheer for his cricket team, the Kolkata Knight Riders.
The "Rab Ne Bana Di Jodi" actor also has two more children - son Aryan and daughter Suhana - with wife Gauri.
On the big screen, SRK was last seen in Farah Khan's "Happy New Year" and will be seen in Maneesh Sharma's "Fan" and Rahul Dholakia's "Raees".
