Kareena Kapoor (Hindi: करीना कपूर; born on September 21, 1980), often informally referred to as Bebo, is an Indian film actress who appears in Bollywood films. Born into a film family where both her parents, Randhir Kapoor and Babita, and her elder sister Karisma were actors, Kapoor faced the media spotlight from a very young age. 
However, she did not make her acting debut until the 2000 film Refugee, which earned her the Filmfare Best Female Debut Award. Her melodrama Kabhi Khushi Kabhie Gham became India's highest grossing film in the overseas market in 2001 and is her biggest commercial success to date. 
After receiving negative reviews for a series of repetitive roles between 2002 and 2003, Kapoor accepted more demanding parts in order to avoid being typecast. Consequently, from 2004 to 2006 she was recognized by critics for displaying greater versatility. 
Her portrayal of a sex worker in Chameli (2004) proved to be the turning point in her career and garnered her the Filmfare Special Performance Award. She later received two Critics Awards for Best Actress at the Filmfare ceremony for her performances in the critically acclaimed Dev (2004) and Omkara (2006).
In 2007, Kapoor earned a Filmfare Best Actress Award for her performance in the Imtiaz Ali directed romantic comedy film, Jab We Met. Although the box office earnings of her films have varied considerably, Kapoor has established herself as one of the leading contemporary actresses in the Hindi film industry. Kapoor's off-screen life is subject to wide media coverage in India with frequent press coverage of her and boyfriend, actor Saif Ali Khan and speculation of a possible marriage. 
Early life and family:Born in Mumbai, Maharashtra into the Kapoor film family of Punjabi Khatri origin, Kapoor is the youngest daughter of actors Randhir Kapoor and Babita (née Shivdasani). She is the granddaughter of actor and filmmaker Raj Kapoor, great-granddaughter of actor Prithviraj Kapoor, sister of actress Karisma Kapoor and niece of actor Rishi Kapoor. According to Kapoor, the name "Kareena" was derived from the book Anna Karenina, which her mother read while she was pregnant with her. She is also often informally referred to as Bebo.
As children, the Kapoor sisters dreamed of becoming actresses. Kapoor was particularly inspired by actresses Nargis and Meena Kumari. However, despite her family background, her father disapproved of women acting because he believed it to be incompatible with their duty to the family. This led to conflict between her parents, and Kapoor's mother ultimately left her father. Kapoor was raised in Lokhandwala by her mother who worked several jobs to support her daughters until Karisma debuted as an actress in 1991. 
Kapoor attended Jamnabai Narsee School in Mumbai before progressing to Welham Girls Boarding School in Dehradun. She studied commerce for two years at the Mithibai College in Vile Parle, Mumbai. However, she disliked her term there and studied only because she was close to her family.
Kapoor then registered for a three-month summer course in microcomputers at Harvard University in the United States. She later developed an interest in law and enrolled at the Government Law College in Churchgate. However, after completing one year at Churchgate, Kapoor returned to her initial plan to become an actress and began training at the Kishore Namit Kapoor's Acting Institute in Andheri. 
Personal life:In 2004, Kapoor began dating actor Shahid Kapoor whom she eventually parted with during the filming of Jab We Met in 2007. In September 2007, speculation began to surface that she was dating Saif Ali Khan. On October 18, 2007, during Manish Malhotra's grand finale show at the Lakme Fashion Week, Khan confirmed their relationship to the media.
Kapoor is very close to her family and has resided with her mother Babita for much of her life. Kapoor and her mother lived together in Lokhandwala and then at Park Avenue in Bandra, Mumbai for several years, and in 2008 Kapoor and her mother purchased adjacent flats in Khar, Mumbai designed by Akshay Kumar's wife Twinkle Khanna. Kapoor says she is an avid reader and swimmer in her leisure time. 
Kapoor's weight and diet have often been scrutinized by the media. In 2006, Kapoor declared that she was becoming a vegetarian to keep her weight in check. Kapoor has denied rumours that she is suffering from anorexia and has attributed her weight loss to yoga and a closely-monitored, balanced diet. When Kapoor lost weight and collapsed on set during the filming of Tashan in 2008, media speculation about her health was rampant. She dismissed the incident as a minor health scare.
