After winning laurels for her superb performance in The Dirty Picture, Vidya Balan is all set to go a notch higher when it comes to experimenting with her looks on screen.

For her debut item number in Vidhu Vinod Chopra's Ferrari Ki Sawaari, the actress is leaving no stone unturned to make sure that she looks her glamorous best. Vidya will not only try 10 different look tests but also wants to hear the scratches of the item song.

Our source in the film's production reveals, "As it is, Vidya has undergone a drastic makeover for The Dirty Picture. So the idea is to go further than that.

Hence she is insisting that we should collectively exploit as many looks as possible for her song, and go with the one that best suits the song that will be eventually finalised.

So 10 different looks are being worked out for her, with inputs from the film's makers and the stylist, apart from the actress herself." Having put on kilos to play 'Silk' in The Dirty Picture, Vidya has been working on losing the excess weight after the film's release.

So it's natural to expect a slimmer and sexier avatar of the actress in her item debut. Interestingly, it seems that it wasn't that the actress instantly agreed to do the item song. "Vidya saw some portions of the film, featuring Sharman Joshi, along with producers Chopra and Rajkumar Hirani.

She took an instant liking to the film and immediately agreed to do the song," reveals our source, adding that the actress is 'super excited' about it. "Besides, she has also extensively discussed it with Chopra, Hirani and Mapuskar, along with the nature of the song and the way it will be shot," points out the source.

On his part, director Rajesh Mapuskar confirmed this saying, "Yes, we are creatively working out the look. There have been all kinds of item numbers and we want this one to be different."
