Although, no official announcement has been made from either side, it is believed that the two will tie the knot post the release of Vidya's upcoming flick Kahani in which she plays a pregnant woman in search of her husband and the father of the child. Probably, the wedding might happen in April or May.
Vidya Balan, who has to her credit super hit films like 'Dirty Picture', 'No One Killed Jessica', 'Paa' and 'Ishqiya', has never confirmed her relationship with Kapoor, the Chief Executive Officer of UTV Motion Pictures, but the two have been spotted together at various events.
Reportedly, the actress is also accompanying Siddhartha to various family functions.
Last year, there was a buzz that the couple got married secretly and even headed to their honeymoon, however, Vidya rubbished all the rumors saying that something like this will never happen in her life.
