Karan proudly announced the birth of his twins through surrogacy in 2017.

He named his son after his late father Yash Johar and Roohi's name is derived by rearranging the letters of his mother Hiroo Johar's name.

Reportedly, Karan plans an intimate party for them with B-Town kids including Taimur, Misha, Laksshya, Adira and others on the guest list.
