A few days ago, we had seen how special invites had been sent to family and friends inviting them to the 75 birthday celebrations. Karan definitely knows how to do things with class and the pictures and video show that it was a grand and chic affair.

Earlier today, Karan posted a collage of his pictures with his mother and said, “Centre of my universe and the big love of my life!!! My mom is 75 today!!!” In all his interviews, he has always attributed all his successes to his mother, who has always been the wind beneath his wings that helped his dreams and aspirations to take flight. He has also mentioned how she has always been supportive of his decisions and been there for him and now, for his kids Yash and Roohi. The mother-son duo share a beautiful bond and our heart is filled with love and happiness after looking at all these celebration pictures. India.com wishes Hiroo Johar a happy and joyous 75th birthday.
