Karan Johar frequently posts updates about his films and personal life on Instagram.

The filmmaker shared a hilarious video of his son Yash wearing a "nepo baby" shirt on Instagram on Saturday. Who handed the shirt to Yash? Karan claimed that the actress forced him to keep her identity a secret.

Karan pointed his phone camera towards Yash as he flaunted his blue tee which had the words, ‘Nepo baby’ written on it. Karan said, “Oh my god, do you know what this t-shirt says, that you are nepo baby?” In response, Yash quips, “Yeah, but I don't want to be launched!” He then runs away, while Karan adds, “What! Who is launching you anyway?”

In the caption, Karan wrote: “He has a mind of his own. I am HAPPY!!! Ps..T shirts gifted to the twins by •••••• ( oops she made me promise I won’t tell).”

In February 2017, Karan gave birth to Yash and Roohi through surrogacy. Roohi is an anagram of his mother's name, Hiroo, and Yash is named after his late father, Yash Johar. In 2019, Karan discussed the difficulties of being a single parent on Pinch By Arbaaz Khan.

Karan told Arbaaz, "I am a single parent, and it comes with its own set of challenges. But that doesn’t mean that a woman and a man have different roles to play. Like I think that’s very stupid. Cause that’s an old world thinking. And I feel like enough love to give my child. And also, I have a mother at home who they call mumma."
