Arjun Kapoor shares a deep relationship with his half-sisters Janhvi Kapoor and Khushi Kapoor. The Kapoor siblings have become inseparable and often hang out and celebrate all the festivals and special occasions together. The bond between them grew stronger after the death of Sridevi, Arjun's father Boney Kapoor's second wife.

In an interview with Pinkvilla, the 2 States actor opened up on the relationship he shared with his half-siblings and death of Sridevi. "You don't always connect to dots. I reacted to situations the way they happened in real-time. A couple of years now today, it's easier for people to assess. My mother taught me to be a good human being, to be as decent to other people as possible. At that moment, I felt it right to lend my support in whatever capacity I could and be there to start with for my father. It also meant that we got a chance to know Khushi and Janhvi. The maturity comes from the fact that I have seen life. If my life was shaken and uprooted at one point and if I can stabilise someone else's to make sure they don't go through the hell that I did."
