"One of Kareena's looks in the film is inspired by Barbie doll," Bhat said.

"One day, while on the shoot, she came out of her vanity van and was ready for her shot. She was wearing a baby pink tube top with a white skirt and I gave her a creamy baby pink lipstain (colour) for her lips. Her hair was straight - and as soon as I saw her, I told her how much she looked like Barbie doll," she said.

In "Kambakkht Ishq", which is produced by Sajid Nadiadwala, Kareena stars alongside superstar Akshay Kumar who plays a Hollywood stuntman. It also stars Hollywood biggies like Sylvester Stallone, Brandon Routh and Denise Richards.

According to Bhat, Kareena's different looks in the film have a lot to do with the progression of her character.

"At first she has a plain Jane look, followed by a cute girl-next-door look and then she ultimately turns into an ultra-glam diva as she plays a model in the film," she said.

Bhat said that Kareena has been made to wear minimum make-up and tied ponytails for the first part of her character, while she leaves her hair open and sports little gloss for her second look.

But later Kareena's eyes are well accentuated with different colours, she added.

"For her glamorous look, I used metallic liners in colours like charcoal, blue, green, grey and played around with a lot of shimmer on her eyes. But what remained permanent for Kareena throughout the film was the creamy baby pink lip colour that I have not used on anyone yet," Bhat said.

Bhat, who was responsible for Deepika Padukone's Chinese looks in "Chandni Chowk To China", says Kareena too loves slipping into the glamorous look.

"She is a girl. Like every other girl, she enjoys getting ready and so I guess she enjoyed slipping into the glamorous character. She liked to get ready for it like any other girl her age would have," she said.

Coupled with Bhat's make-up techniques, Mumbai-based hairstylist Pompy Hans worked on Kareena's hair for the film.

"She has such a glamorous role in the film. I tied her hair into neat ponytails for her first look, gave her simple and straight hair for her second and then experimented with a layered haircut, a nice bouncy blow dry on her hair and even coloured her hair copper, mostly dark blonde tints for her model-like look," Pompy said.
