Vidya not allowed to work with Shahid?

Bollywood actor Vidya Balan was reportedly considered for Vettai remake opposite Shahid Kapoor. The lady, however, was ruled out by her beau Siddharth Ray Kapoor. Wonder why?
Siddharth apparently said that the role wouldn’t do justice to her talent as an actress, reports Mid Day.
A source, however, reveals to the tabloid, that Siddharth did not want Vidya to star opposite rumoured ex-flame Shahid Kapoor. Vidya and Shahid had became close during the making of Kismat Konnection.
This is not the first time Siddharth has stopped Vidya from working with a rumoured ex-beau. The Dirty Picture actor had to say no to John Abraham for the same reason.
“She didn’t want to be paired with John Abraham due to strong reports of their affair while filming Salaam-E-Ishq,” a source told the tabloid.
About Vettai
Vettai, a Tamil action flick was written and directed by N Linguswamy. The film stars R Madhavan, Arya, Sameera Reddy and Amala Paul in the lead roles. The film revolves around two brothers, the elder being sensitive to violence and the younger being a jobless rogue, settled in Thoothukudi. Vettai was released worldwide on 14 January 2012.
The Hindi version of the fim is also being directed by N Linguswamy, but actor Shahid Kapur asked him to "get a good Hindi dialogue writer". Shahid joined the project on the condition that a reliable and sound Hindi dialogue writer be brought into the project. So Prasoon Joshi is likely to pen the dialogues for the movie that will go on floors in June.
Director Linguswamy told IANS, "I cannot communicate in Hindi. And the dialogues were not being translated properly. That was the main problem. Now my producer UTV is hiring a dialogue writer of their choice. That writer will be getting together with the Tamil dialogue writer of Vettai to get the essence of the dialogues. "
