Bollywood superstar Shah Rukh Khan is known to be a workaholic and during one of his long hour shifts on the sets, the actor had a surprise young visitor - his youngest sonAbRam.

SRK, who has been working 16 hours at a stretch for his upcoming film 'Happy New Year' team, had AbRam on the sets and it made his day, reports the Times of India.

Shah Rukh, who will soon be seen in choreographer-turned director Farah Khan's 'Happy New Year', took to Twitter to share his experience about having AbRam on the sets.

Shah Rukh Khan, who keeps his fans updated about his three children, has said that he prefers not to bring his youngest son AbRam in public and says he is also not overtly happy talking about him.

In a recent interview, Shah Rukh said, `I am not overtly happy talking about him. He is my baby and nobody else's. You can come home and see him if I allow you to come in my house.`

`He (AbRam) is not meant for flashbulbs. I don'twant him to be a participant in this circus of public life that Iam a part of. That is what I do... Public life... The good, bad, ugly, goodness of media, the strangeness... I am part of it, not my children,` SRK further said.

Shah Rukh Khan's 'Happy New Year' is scheduled to release this Diwali on October 24. The film also features Deepika Padukone, Abhishek Bachchan, Sonu Sood, Boman Irani and Vivaan Shah. The actors of the film inckuding Shah Rukh Khan, Boman Irani and Sonu Sood were threatened by underworld don Ravi Pujari.
