New Delhi, Mar 5 (UNI) Bollywood filmmaker Karan Johar, who has become a father to twins, Roohi and Yash, born through surrogacy, today said he feels enormously blessed to be a parent. 'I am ecstatic to share with you the most wonderful additions to my life, my children and lifelines; Roohi and Yash. I feel enormously blessed to be a parent to these pieces of my heart who were welcomed into this world with the help of the marvels of medical science,' Karan posted on social media. 'This was an emotional yet well thought out decision which I have taken after considering all the responsibilities and duties that come with being a parent. I have prepared myself mentally, physically, emotionally and logistically to ensure that my children get all the unconditional love, care and attention from me. I have submitted to the fact that my children are my world and priority. My works, travels and social commitments would have to take a backseat and I am prepared for that. By the grace of God I have the most caring and supportive mother who will be an integral part of the upbringing of her grandchildren and , of course, friends who are family, ' the filmmaker said. Karan also extended gratefulness to the surrogate who “fulfilled my lifelong dream and provided a warm, loving and nurturing environment to my children before bringing them into this world.” “She will always remain in my prayers,' Karan said. Karan also extended gratitude to IVF specialist Jatin Shah, who was also instrumental in the successful birth of superstar Shah Rukh Khan and his wife Gauri’s son Abram who was also born through surrogacy. Karan's daughter has been named Roohi, a rearrangement of his mother’s name Hiroo and the son has been christened Yash, on his late father’s name. UNI AR PY SV 1333
