Sangeeta Bijlani is all set to make a comeback in Bollywood. Grapevine has it that she has been signed to play the role of a high society fashion patron in Onir's upcoming film Shab. It is said that the film will be a South Delhi based love story. If we recall Salman Khan's ex-girlfriend had been completely out of the Bollywood scenario for over two decades, but she suddenly started making guest appearances this year at Jai Ho and O Teri! screenings.
