Karan Johar becomes our not-so-secret Santa as he grants our wish and gives us the first public appearance of Yash and Roohi. KJo's best production for sure! Filmmaker Karan Johar, who welcomed twins Roohi and Yash via surrogacy earlier this year, says he has a lot of expectations from his children. "Just like any other parent, I too have a lot of expectations from you (Roohi and Yash). This expectation is necessary because we build our foundation based on them. Your grandmother (Hiroo Johar) has told me and will also tell you that bookish knowledge is not everything," Karan revealed on Shah Rukh Khan's show TED Talks India Nayi Soch.
