How come Pooja uses surname Sippy. I believe she is Nishi & Yash's daughter. It's okay and normal that her mother uses her maiden name but her father's name is Kapoor and she uses surname Sippy!! Technically she would be using Pooja Kapoor na?
I'm not aware if there is any trend to use mother's surname or so. Pardon me in that case. But just a thought came across so shared.
