Karan Johar remembered his late father Yash Johar and shared, "My biggest blessings, my biggest strengths, my biggest critics & my biggest reasons for everything I do Thank you for making me a father Roohi & Yash! Dada loves you very very much..And thank you papa, for being the guiding light. If today I can be even half of the father figure as you, to my kids - I will consider that as my biggest victory.#FathersDay." (Photo: Karan Johar/Instagram)
