Kareena caused a flutter when she referred to Katrina as her sister-in-law, and even said that she would dance to Katrina's hit songs on her cousin Ranbir Kapoor's wedding. Ranbir and Katrina are rumoured to be dating, and Kareena's comment only fuelled those rumours. Now Kareena has spoken out about it. At the Big Star Entertainment Awards red carpet here Wednesday, when Kareena was asked about calling Katrina her sister-in-law, she said: 'It ('Koffee With Karan') is a fun show and it is meant to be like that and that (Katrina as my sister-in-law) is not meant to be taken too seriously. It is not such a big deal.' 'I am his (Ranbir Kapoor) elder sister and being that, I can say whatever I want to,' she added. Kareena's father Randhir and Ranbir's father Rishi are siblings.
