She has also appeared in Telugu and Malayalam films. She was voted the sexiest Asian woman in the world by Eastern Eye in the years 2008, 2009 and 2010.

Kaif was born in Hong Kong, to an Indian Kashmiri father, Mohammed Kaif, and an English mother, Susanna Turquotte, both of whom are British citizens. Her parents divorced when she was very young. Kaif once stated, "My dad, unfortunately, and not out of choice, has had no influence on our upbringing, on our religious or social or moral bearings." When she came to India, she changed her surname to Kaif, because it was Indian in origin. Furthermore, Ayesha Shroff has maintained that the actress' original name is Katrina Turquotte. Kaif has seven siblings; a brother and six sisters. From Hong Kong, she and her family moved to China, then to Japan. From there she went to France when she was 8, and thereafter lived for a few months at a time in Switzerland, Poland, Germany, Belgium, and other European countries. Then she moved with her family to Hawaii, and eventually to her mother's home country of England.
