A source from Juhu says that Vidya Balan's producer beau, Siddharth Roy Kapoor is a very possessive kinda guy. He doesn’t want her to work with the actors she has been linked with. Apparently, when Tamil director Linguswamy suggested casting Balan for the Hindi remake of his film 'Vettai', Siddharth vetoed it saying the role wouldn't do justice to her talent as an actress.

However, our insider reveals that the producer wasn't comfortable with the idea of casting his actress girlfriend opposite Sasha since they were rumoured to be an item during the making of 'Kismet Konnection'.

Incidentally, she’s believed to have turned down Sanjay Gupta and Ekta Kapoor’s joint venture for a similar reason. "She didn’t want to be paired with John Abraham due to strong reports of their affair while filming 'Salaam-E-Ishq'," recalls our souce.
