Actress Kalki Koechlin says she wishes to work on screen with all the Khans of Bollywood, but she has a softer corner for Shah Rukh Khan. Asked if she wants to work with any of the top Khans of the industry, Kalki told IANS: "I want to work with all three Khans, but if you ask me my favourite, it has to be Shah Rukh. Shah Rukh is my childhood crush. I met him few times in real life as well and he is very charming."
