AbRam, who was born through surrogacy last year, made his first big screen appearance in the end credits of Farah Khan-directed HNY, and the doting dad is excited to "show off".
"While making the film, I used to hardly get any time to come home...(thanks to) late night shootings and all. One day, he had come over to the studio," the 48-year-old told IANS on phone from Mumbai.
"I made him sit on the stage and I started dancing with him. Farah asked me to let her allow to shoot my son and I said: 'Shoot it'. Now, when I see it, it's nice," Shah Rukh said.
HNY raked in Rs.108.86 crore - the biggest opening weekend that a movie has got at the box office in India.
"It's nice to know that my son's film has done such good business. I can show off that my son is a big star," said the father of three children.
On the festive occasion of Eid, Shah Rukh unveiled a photograph of himself cuddling AbRam.
SRK also has two teenage children - son Aryan and daughter Suhana - with wife Gauri.
