Kajol, Bold and Beautiful at 40

One of Bollywood's most gifted actresses, Kajol gave it all up for a life of domestic bliss. The actress who made the entire nation fall in love with her in movies such as Dilwale Dulhania Le Jayenge, Baazigar and Yeh Dillagi has only recently become very active on Bollywood's social circuit.

There's good news for her fans. The actress, who was last seen in Karan Johar's 2010 movie, My Name Is Khan, will be making a comeback with a woman-centric film to be produced by her husband actor Ajay Devgn.

Here's a pictorial journey through her life as she turns a year older.

Kajol, who is of Bengali-Marathi descent, in fact belongs to a family tree with a long respectable history in the Indian cinema and hence, acting is embedded deep within her genes.

Kajol's mother is yesteryear actress Tanuja, who has starred in films like Yaarana and Mere Jeevan Sathi, while her father was a popular producer-director Shomu Mukherjee.

Kajol is also related to star singer-actor Kishore Kumar - her paternal grandfather was married to the maestro's sister.

It doesn't end there: her maternal aunt, Nutan, was one of the leading actresses of her time.

Her cousin, actor Mohnish Behl, was a popular villain during the 90's; Ayan Mukerji, another of her cousins, is a successful director.

Kajol is also one half of a Bollywood power couple. Actor Ajay Devgn and Kajol, who co-starred in films like Pyaar Toh Hona Hi Tha (1998), Raju Chacha (2000) and Ajay's debut direction film U, Me Aur Hum (2008), married on February 24, 1999.

Four years after their marriage, which surprised Bollywood as a marriage of opposites, Kajol gave birth to the couple's first child, daughter Nysa.

Their second child, son Yug, was born on September 13, 2010.

Kajol's first film was Baazigar in 1993 in which she starred opposite Shah Rukh Khan. The film was a blockbuster hit and catapulted both its lead actors to the A-list. Her on-screen chemistry with Shah Rukh Khan made them the nation's favourite jodi.

In 1994, she starred in Yeh Dillagi opposite Saif Ali Khan and Akshay Kumar.

Not only was the film declared a hit, Kajol also received her first Filmfare nomination in the Best Actress category for her performance.

In 1995, Dilwale Dulhaniya Le Jayenge, Aditya Chopra's debut film as director, once again paired Kajol with Shah Rukh Khan. The romance-drama redefined a whole genre of films. In fact, it still runs to packed houses in the Maratha Mandir theatre in Mumbai.

In 1997, Kajol won her third Filmfare Award for Best Actress (this time, South), for the film Minsaara Kanavu, in which she starred opposite Prabhu Deva and Arvind Swami.

The film, which was released in Hindi as Sapnay, had almost twenty A R Rahman compositions, like Ek Baghiya and Chanda Re.

1997 ended on a good note, because she finished with another blockbuster hit in Ishq, opposite future husband Ajay.

In 1998, Kajol appeared in her first film with Salman Khan.

Pyaar Kiya To Darna Kya, written and directed by Salman's younger brother, Sohail, was one of the biggest hits of the year. She played a restricted sister to Arbaaz Khan's overbearing brother. Arbaaz, of course, is also Salman's brother, making it a Khan family affair.

There was more success in store for Kajol in 1998 with Pyaar To Hona Hi Tha opposite Ajay Devgn. The film was a remake of the Hollywood flick French Kiss.

However, her biggest hit of the year was opposite Shah Rukh Khan once again. Kuch Kuch Hota Hai Karan Johar's debut film as a director, went on to become a runaway success, the biggest film of the year in both India and abroad.

At the Filmfare Awards, she achieved the unique feat of being nominated for three films within the same year and, beating competition from basically her own self, winning her her second Filmfare Best Actress Award for Kuch Kuch Hota Hai, her fourth overall.

Kajol then went on to star opposite Anil Kapoor in the moving family drama Hum Aapke Dil Mein Rehte Hain. She received another Filmfare Best Actress nomination, but lost to Aishwarya Rai for Hum Dil De Chuke Sanam.

After a bland outing in 2001's Kuchh Khatti Kuchh Meethi (featuring her in her second double role), she bounced back to the top with Karan Johar's Kabhi Khushi Kabhie Gham, which became the second highest grossing film of her career, behind Dilwale Dulhaniya Le Jayenge. No surprises for guessing who her co-star in the film was, once again: Shah Rukh Khan.

K3G, as the film is popularly abbreviated, won Kajol her third Filmfare Best Actress Award, and fifth overall.

After K3G's phenomenal success, Kajol decided to take a five year break from the movies to concentrate on raising her daughter.

Most actresses don't really make an impression with their comeback vehicles (case in point: Madhuri Dixit's damp squib, Aaja Nachle, but here again Kajol proved herself a trendsetter.

She returned to the big screen in 2006, with Kunal Kohli's Fanaa, one of the highest grossing films of the year. The film also marked Aamir Khan's first project with Yash Raj Films. Portraying a blind Kashmiri girl who falls in love with a Kashmiri terrorist in the film, Kajol won her fourth Filmfare Best Actress Award and sixth overall.

In 2008, her husband, Ajay Devgn, debuted once again--this time as a director. U, Me Aur Hum, which starred Ajay as Kajol's reel-life husband, performed moderately at the box office. Kajol's sensitive portrayal of an Alzheimer's patient and Ajay's immaculate direction were both critically applauded.

In 2010, she reunited with Shah Rukh Khan in Karan Johar's My Name Is Khan.

A raging blockbuster, it marked the jodi's on-screen return after nine years and Kajol won her fifth Filmfare Award for Best Actress. She became one of two actresses to have five Best Actress wins, the other actress being her aunt Nutan.

Kajol is also UN's hand washing ambassador and advocate of a soap brand's 'Help a Child Reach 5' campaign.

Kajol is reportedly making a comeback with a woman-centric film to be produced by her husband actor Ajay Devgn.

Here's wishing Kajol a very happy birthday and a great year ahead.
