Cheaper the better for Katrina Kaif

Katrina Kaif is undergoing a transformation for her role as an item girl in Farah Khan's Tees Maar Khan. She is slowly turning aggressive and loud.

She has made sure her manner turns loud even when it's 5am in the morning. She is also making an effort to look strikingly different in each of the item songs, which Farah and her assistant, Gita, have choreographed.

To get her character's look right, Katrina has been shopping for clothes and accessories herself. She has been visiting small shops that sell cheap stuff to give her character an authentic look. She feels that it's a bit of a challenge to do a complete look but working in Rajneeti has taught her that every accessory brings the character in.

The actress has also been brushing up her knowledge on Bollywood's item girls by going through some of the popular item numbers like Mumtaz's Tik tiki mera dil bole from Humjoli (1970) and Bipasha Basu's Beedi from Omkara (2006).

Akshay Kumar, Katrina's co-star on Tees Maar Khan has been advising her to just go wild when dancing on camera as it will help her character.
