Karishma Tanna on an image makeover spree, but why?

Karishma Tanna seems to have done a complete image overhaul as she steps into the shoes of her character in Devang Dholakia's film, Tina and Lolo.

Her last outing in Grand Masti had her as a nagging wife.

In her next, she will be seen playing the role of a hacker who gets a thrill riding bikes in the fast lane. She says,`I have spent countless hours researching the world of hackers and gadget freaks. I have read up on these people extensively and tried to understand how they think.

In addition, I have spent the past couple of months mastering the art of riding bikes. Most people would think this is easy but handling a Harley is no easy task. My character Lolo is an alpha female and as such I have had to work hard on my body language.`
