28-year-old Varun, who is sharing screen space with the superstar for the first time, said he had a great time playing with Shah Rukh's youngest child AbRam.
Varun added Shah Rukh has been warned by Gauri not to talk much about AbRam.
"I most definitely played with him... He is very fond of me... I will not talk much about him because Gauri ma'am has warned Shah Rukh Sir (SRK) not to speak about Abram and so I can't talk at all about him," Varun said on the sidelines of the ongoing MAMI Mumbai International Film Festival here.
"He (Shah Rukh) is an outstanding father... I have never met a father like him... He goes weak in his knees. If I ever become a father I would want to be as good as him. Even in his busy time he gives as much time as possible to his kids," the "Main Tera Hero" star said.
The "Chennai Express" star will be turning 50 on November 2 and Varun would like to gift a play station to the superstar.
