Actress Kareena Kapoor Khan has worked with Shah Rukh Khan, Aamir Khan, Saif Ali Khan and Salman Khan on the big screen. She had delivered hit films with all of them but she feels most "privileged" to join creative forces with Irrfan Khan in "Angrezi Medium". When asked about how she is preparing for the role, Kareena Kapoor Khan told IANS here: "Oh God, I am super excited for this film. I have worked with all the Khans -- Shah Rukh, Salman, Aamir and Saif. But for me, it is an honour and privilege to work with Irrfan Khan. "He is the pioneer, one of the finest actors among all the Khans if I may say, and he is the biggest Khan for me. So, I had to tick that box of acting with Irrfan Khan. I know it is a small role but that does not matter. I know I am too excited, and I am really looking forward to this one." On the work front, Bebo will start shooting for the film from May 15. It also features Radhika Madan and Pankaj Tripathi. Kareena has finished shooting the Akshay Kumar-starrer "Good New".
