The much-hyped relationship and wedding of actress Nayanthara and director-actor-choreographer Prabhu Deva has been called off. According to a source close to the couple who confirmed this news, the two decided to call it quits a few weeks back. Explains the source, "Prabhu and Nayan were in a relationship for more than three and a half years. She devoted herself to him. In fact, as everyone knows, she gave up her extremely successful career in the south in the hope that they would get married and settle down soon. She was the top actress in the south when she decided not to sign on any more new movies." Over recent months, there were rumours doing the rounds that all was not well between the couple. Says the source, "The stories that were doing the rounds that Nayanthara was creating issues for Prabhu are not true. In fact, she was the one who tried her best to make this relationship work." A few months back, Prabhu Deva issued a press statement stating that he'd get married to the actress in the near future and she was welcome to sign on any films she wanted. But the actress did not take on any new projects in the last few months nor discuss her marriage with the media. Suddenly, there was news that the couple was living together and she was visiting him regularly on the sets of his Bollywood flick Rowdy Rathore. This news is also completely false, states the source, adding that it was as a result of the recent break-up that Nayanthara decided to return to films. Apparently, she was planning to settle down as a homebird but once they broke up a few weeks back, she decided that she would get back to her career.
