Unlike other artistes from foreign lands, Katrina did not experience any difficulties in getting a visa nor of getting it extended in India.
She was discovered at age 14 as a model for a jewelry campaign.
When moving to India, she worked for photographer Atul Kasbekar and did commercials for Fevicol, Lakme and Veet among others.
She is very particular about her clothes which she wears a bold outfit on screen or for ads, but she feels more comfortable in not-so-revealing clothes in personal life. And the one thing she hates is make up.
She refuses to speak about her personal life in the media.
Besides walking the ramp for several top designers and being on magazine covers, Katrina has also been the stunning face of Estelle jewelery, Lakme, Pantene, Veet, Kodak cameras, L'Oreal, Samsung, LG etc.
She doesn't do ramp shows anymore.
She was chosen as the face of the year for the Lakme India Fashion Week (2005).
Her favorite Indian designers are Rina Dhaka, Tarun Tahiliani, Rocky S.
Her favorite international designers are Armani, Versace, Miu Miu.
"It's not my style to either wear minimum clothes, to strip or to even be comfortable with a sex-symbol label. I just want to do good work instead of sporting such meaningless tags. Sex sells, but to a small extent, not always. And this is what filmmakers have to accept. The exposure has to be relevant to the film and its characters and not forced for the sake of titillation. On the contrary, some of the greatest Indian films have been devoid of all these sexual trappings. I know my comfort zone in today's Indian culture and society."
Her thoughts on Bollywood accepting her, being an outsider British girl, into Indian cinema: "I have no complaints. I think I'm especially lucky. As you said, I've come from outside and I'm not even anywhere closely connected. But I have absolutely no problem here. People have been more than welcoming, even before I was ready. There was a time when I felt that I need to take time to understand more about the industry, the workings of it. I was doing my modeling, which I really wanted to do at the time. So that's why even my entry into films was later than people expected." (Stardust magazine, July 2006)
"I've been very blessed, I think, or what do you call it... mmm... lucky to get at this stage what I have। It's not like I've come from acting school and done work at an academy or something. I feel I've been given a very huge chance and opportunity." (Stardust magazine, July 2006)
