Vidya Balan has received rave reviews for her performance in "The Dirty Picture" and, impressed by her dare-bare act, Kareena Kapoor is said to have given Madhur Bhandarkar the go-ahead to shoot scenes on similar lines for "Heroine".

But Vidya, 32, feels no one can cross the benchmark set by "The Dirty Picture".

"I think, no one could get dirtier than this. They can make a 'Heroine', but will not be able to make a 'Dirty Picture', " said Vidya who started her career in Bollywood with Pradeep Sarkar's "Parineeta" in 2005.

She also says that she has never been in the race to become the number one heroine.

"I have never been part of the race and I am still standing by myself. I am just very, very happy that I have got the films that I have, especially 'The Dirty Picture' which for me is a huge landmark.

"I have had critical and commercial success before, but this is something different. 'The Dirty Picture' is a landmark in many, many ways and not just for me, " said the 33-year-old actress at a press conference to celebrate the success of the film.

Vidya's next films are "Kahaani", directed by Sujoy Ghosh and Nikhil Advani-directed "Chand Bhai" opposite Akshaye Khanna.
