Megastar Chiranjeevi is reportedly set to romance B-town queen Aishwarya Rai Bachchan in his 156th film, billed to be a socio-fantasy. Former Miss World would be arriving in Tollywood, and it is touted to be a casting coup. ‘Chiranjeevi and Aishwarya Rai pairing would be a sensational combination, and the film is bound to trigger hype and hoopla across India. It would be another magnum opus from Tollywood,’ says a source, who claims that the negotiations are underway with Aishwarya Rai and a deal could come through soon.
