Filmmaker Karan Johar is celebrating his 48th birthday on 25th of May and has been recieving adorable wishes from friends, fans and family. Now, Karan shared a video from his popular Instagram series #lockdownwithjohars wherein he was seen celebrating his birthday with his family. The video shows his little munchkins Yash and Roohi blowing candles and cutting cake as their ‘dadda’ asked them to do so. The brother-sister duo hilariously asked Karan not to eat cake as he will gain weight. Karan’s mother Hiroo Johar also made an appearance in the video!
