Karan took to Twitter to share the picture where his late father is holding the hand of the "Kuch Kuch Hota Hai" star.
"Papa and @iamsrk....#memoriesforever," he captioned the pic.
An emotional Shah Rukh too commented on the photograph.
"Oh how I miss my friends who are gone... Love u Tom Uncle and miss you most," he wrote.
The "Dilwale" star and Karan last worked together in "My Name is Khan" five years back. They are going to team up again in his upcoming production venture, which will be directed by "English Vinglish" helmer Gauri Shinde and stars Alia Bhatt opposite the superstar.
