A lot of Bollywood celebrities have penned some interesting books and it seems like Twinkle Khanna is all set to join the bandwagon. While she does run a successful business of interior designing, it looks like Twinkle now wants to expand and explore. According to trade buzz, the actress will be jotting down three books as part of a deal. It may not be a biography of her popular husband Akshay Kumar as no details of the book deal have been revealed. Twinkle, daughter of late superstar Rajesh Khanna and Dimple Kapadia, had tried her hand in Bollywood but failed to make a mark.
