Karan, who has worked with Shah Rukh in films like "Kuch Kuch Hota Hai", "Kabhi Khushi Kabhie Gham" and "My Name is Khan", shared a photograph of AbRam with his mother Gauri Khan on Twitter on Monday.
"The adorable AbRam is turning out to quite the poser! Stealing the thunder from his talented and beautiful mother," Karan captioned the image.
AbRam was born via surrogacy in 2013. Besides him, Shah Rukh and Gauri also have another son named Aryan Khan and a daughter Suhana Khan.
