Playing pregnant woman was cakewalk for Vidya

If she effortlessly essayed the role of a sex symbol in 'The Dirty Picutre', it was a cakewalk to play a pregnant woman in search of her husband in 'Kahaani', says Vidya Balan.

'It was not tough at all. During our college life, we all friends used to do all the nautankis and these stand-up items. And my favourite role would always be of a pregnant woman. So the walk and all came to me very naturally,' Vidya, 33, told reporters here.

Vidya ruled Bollywood as Silk last year and it seems she wants to take it forward with 'Kahaani' as she is aggressively promoting the movie. If she dressed like her character for the promotion of 'The Dirty Picture', the actress appeared with a baby bump at the 'Kahaani' promotional event.

'Kahaani', scheduled to release March 9, is not the first film to feature her as a mother -- in 'Paa' and 'Heyy Babyy' too she had played a mom.

Besides her hard work, Vidya can't stop praising director Sujoy Ghosh's efforts and said: 'He is very energetic. We managed to shoot continuously for 64 days without any break. Sujoy would not let the mood drop.'

Vidya, who started her career with Pradeep Sarkar and went on to work with acclaimed directors like Priyadarshan, R. Balakrishnan and Abhishek Chaubey, hasn't got an opportunity to repeat her directors.

When asked about this, she said: 'I don't make any rules. I would be happy to work with the directors with whom I have already worked. Few times it didn't work out. May be in future I will work with them. I am very greedy.'

Her recent was with director Milan Luthria - they teamed up for 'The Dirty Picture' and the film became a super-duper hit.
