Born in Hong Kong, Kaif and her family lived in several countries before she moved to India. She received her first modelling assignment as a teenager and later pursued a career as a fashion model. At a fashion show in London, filmmaker Kaizad Gustad spotted Kaif and decided to cast her in Boom (2003), a critical and commercial failure. While filming in India, Kaif received modelling assignments and established a successful modelling career. However, filmmakers were hesitant to cast her due to her poor command of Hindi. After appearing in the successful Telugu film Malliswari (2004), Kaif earned commercial success in Bollywood with the romantic comedies Maine Pyaar Kyun Kiya? (2005) and Namastey London (2007). She followed with a series of box-office hits, but was criticised for her acting, repetitive roles and inclination to male-dominated films.

 

Kaif's performance in the 2009 terrorism drama New York was better received, earning her a Filmfare Award for Best Actress nomination. After roles in Ajab Prem Ki Ghazab Kahani (2009), Raajneeti (2010) and Zindagi Na Milegi Dobara (2011), she received her second Filmfare nomination for her performance in Mere Brother Ki Dulhan (2011). Kaif featured in the thrillers Ek Tha Tiger (2012) and Dhoom 3 (2013), both of which rank among the highest-grossing Bollywood films of all time. Despite receiving mixed reviews from critics for her acting prowess, she has established herself as a commercially successful actress of Hindi cinema.

 

In addition to acting, Kaif is involved with her mother's charity and participates in stage shows. She is guarded about her personal life, which is a subject of media scrutiny. Her background has also been a topic of discussion, with some sources accusing her of fabricating her history.
