How/Where do I get in touch with Rajkumar Hirani (of "Munnabhai" fame)

Tweet

Hello guyz, I had been reading this brilliant book and my collegue just narrated this strange incident that happened with her, and when I considered both the things (the part of the book I was reading and the strange incident) and have suddenly got a great script idea for "Munnabhai 3". But I dont really know anyone (I mean anyone) from the film industry, and I want to get in touch with Rajkumar Hirani (director of both Munnabhai movies). Can you suggest me any contact details, or any idea of how to get in touch with him?? Please help!!
