Kareena Kapoor Khan has maintained that she is more of a friend to both of Saif Ali Khan's kids, Sara and Ibrahim. When asked about her relationship with Sara earlier, she said, ?I?ve always been open about it. I don?t know why that is such a big deal. It has nothing to do with the person that I am; love and marriage have nothing to do with my professional career. I?ve never understood that, and I?ll never understand why people think that way. Things are changing now; people have become more open about their relationships than they were 20 years back.?
