On Friday, after an event in the city, Karan Johar flew off to New York to be with his mother, Hiroo Johar, who will undergo a back surgery there. She had flown out the day before.

A friend of the filmmaker told Mirror, “Karan has gone away for a month. He may fly back to Mumbai for a couple of days if something important comes up, otherwise he will be by his mom's side.“

Karan is very close to his mother and earlier this year, he bought a fully furnished, duplex apartment in a 12-storey Bandra building and moved into it on her birthday. It was always Hiroo's dream to live in a sea-facing apartment.

Karan remained unavailable for comment.
