Born into a family where her parents, 
Randhir Kapoor and 
Babita, and elder sister 
Karisma were actors, Kapoor faced the media spotlight from a very young age, but did not make her acting debut until the 2000 film 
Refugee. Her 
melodrama Kabhi Khushi Kabhie Gham... became India's highest-grossing film in the overseas market in 2001, and is one of her biggest commercial successes to date. After receiving negative reviews for a series of repetitive roles, Kapoor accepted more demanding parts in order to avoid being 
typecast, and was consequently recognized by critics for displaying greater versatility as an actress. Her portrayal of a sex worker in 
Chameli (2004) proved to be the turning point in her career and she was later noted for her performances in the critically acclaimed projects 
Dev (2004) and 
Omkara (2006).
In 2007, Kapoor received the 
Filmfare Award for Best Actress for her performance in 
Jab We Met, a 
romantic comedy directed by 
Imtiaz Ali. She went on to play the lead female role in the thriller 
Kurbaan (2009), for which she earned critical acclaim, and the drama 
3 Idiots (2009), which became the 
highest-grossing Bollywood film of all time. Having done so, Kapoor has established herself as a leading actress of the Hindi film industry. In addition to movie acting, Kapoor is a regular stage performer and has launched her own clothing line in association with being the brand ambassador for the retail chain 
Globus. Her off-screen life, including her relationship with actor 
Saif Ali Khan, is the subject of wide media coverage in India.
