Kajol was born on 5 August 1974. Her father Shomu Mukherjee was a Hindi film director and her mother Tanuja was an erstwhile Bollywood actress. Her younger sister, Tanisha Mukherjee is also an actress. Kajol was one of the most successful actresses of her generation. She made her acting debut in Hindi films with Bekhudi in 1992. At that time Kajol was only in school.
Post Bekhudi the acting bug bit her hard enough for her to quit her studies and enter the film industry. In 1993 she acted alongside Shahrukh Khan in Baazigar. The movie was a huge success both critically and commercially and helped the careers of both Shahrukh and Kajol in a big way.
The two then acted alongside each other in Dil Waale Dulhaniya Le Jaayenge in 1995. The movie was not only successful but achieved cult status and it also catapulted both Sharukh and Kajol to the top of their game. They were now the hottest pair in Bollywood and its biggest superstars. Kajol then went on to act alongside Shahrukh in Kuch Kuch Hota Hai in 1998 and Kabhi Khushi Kabhi Gham in 2001. Both the films were blockbusters and it seemed as if the pair could do no wrong. Her performances in these films also earned her three Filmfare Awards in the Best Actress category.
On the side she also acted in films like Gupt in 1997 and Dushman in 1998. She earned praise for her role in both the films, thus proving she could do a great job even when she wasn’t paired opposite Shahrukh Khan. She then took a sabbatical from films as she wanted to concentrate on raising a family with her husband Bollywood superstar Ajay Devgn.
But, in 2006 when she made her comeback with Fanaa opposite Amir Khan, she was welcomed back by her fans with open arms. Also, she received her fourth Filmfare Award for Best Actress, for her role in Fanaa.
In the following years she acted in films like U Me Aur Hum (2008), We Are Family and My Name Is Khan (both 2010). For My Name is Khan she received her fifth Best Actress award at Filmfare. As far as her personal life is concerned, Kajol has been in a relationship with Ajay Devgn since 1995. In 1999, they married, and she gave birth to their daughter, Nysa, in 2003 and their son, Yug, in 2010.
