The name 'Kareena' is derived from the book Anna Karenina, which her mother read while she was pregnant
While growing up, Kareena was highly inspired by the acting style of Nargis and Meena Kumari.
Since her parents separated owing to differences, Kareena was raised by her mother Babita. Her mother and father, Randhir Kapoor, reconciled some years back.
Kapoor went to Jamnabai Narsee School in Mumbai, and later to Welham Girls' School in Dehradun.
She later studied Commerce for two years at Mithibai College in Vile Parle.
After developing an interest in law, Kareena even enrolled herself at the Government Law College, Mumbai.
However, she soon lost interest and, like elder sister Karisma, decided to pursue a career in films.
Kareena took her initial acting training from Kishore Namit Kapoor, a member of the Film and Television Institute of India (FTII).
Kareena was supposed to debut with 'Kaho Naa... Pyaar Hai' (2000), but abandoned the project in the filming stage as she felt she wasn't being given enough prominence.
She eventually debuted with 'Refugee' in the same year
Though 'Asoka' flopped, the film was selected for the Venice and 2001 Toronto International Film Festivals.
Kareena gained critical acclaim for her role of a sex worker in 'Chameli' (2004) and a riot victim in Dev the same year
Commercially, her most successful films include 'Jab We Met' (2007), '3 Idiots' (2009), 'Golmaal 3' 2010) and 'Bodyguard' (2011).
Kapoor has been part of several stage shows and world tours since 2002.
Apart from acting, Kapoor has contributed as a co-author to three books: an autobiographical memoir, and two nutrition guides.
She has also launched a clothing line in association with a famous retail chain.
Kareena's personal life has been constantly in the limelight. She first dated Shahid Kapoor before dumping him and falling for the charm of Saif Ali Khan.
