The actress has edged out pretty lass Deepika Padukone for a role in Shankar's "Robot". The film revolves around a scientist who builds a robot to help mankind and everything goes swell till the robot develops a mind of his own… so although the script may not be too original the combination of Rajni and Ash sure seems something to watch out for. If you think that the Bachchan bahu came cheap think again! She is believed to have charged a whopping 1.5 crore rupees for the role…!
