Katrina Kaif's Fitoor at 31

Katrina Kaif is box office gold as she turns 31. Her biggest hits recently include blockbuster action movies like Dhoom: 3 and Bang Bang!. She has big banner projects such as Jagga Jasoos, Phantom and Fitoor coming up. Here's a look at her Bollywood journey as she turns a year older.

British Katrina Turquotte was born on July 16, 1984 in Hong Kong. Katrina's parents divorced when she was young.

Katrina, who has seven siblings, was raised in Hawaii and later moved to England.

In Hawaii, 14-year-old Katrina was scouted by an agent and began modelling. Her first assignment was for a jewellery campaign.

Katrina continued her modelling career in London, appearing for brands such as La Senza.

Katrina stirred up quite a fuss with her Bollywood debut in Kaizad Gustad's Boom in 2003. All of 18, she made headlines for her uber-glamorous bikini-clad role but the film was a flop and critics were harsh about her performance.

After Boom bombed at the box office and her sketchy command of Hindi proved a major obstacle in bagging Bollywood roles, Katrina appeared in three Southern language films - the Telugu Malliswari and Allari Pidugu and Malayalam language Balram vs Taradas.

2005 gave her a breakthrough in the form of an extended cameo as Abhishek Bachchan's NRI girlfriend in Ram Gopal Varma's Sarkar.

She also had a major role in rumoured-beau Salman Khan's film Maine Pyaar Kyun Kiya in 2005.

In 2007, Namastey London with Akshay Kumar made Katrina a bona-fide star. She cemented her position with films like Apne (2007), Partner (2007) with Salman and Welcome (2007) with Akshay.

A year later, Katrina's first negative role, in Abbas-Mastan's twist-ridden Race, fetched crores at the box office.

Her fourth pairing with Akshay Kumar in Singh Is Kinng (2008) also rocked at the box office.

But her near-perfect run at the box office, which led to her being described as every director's lucky charm, came to an abrupt end with Atul Agnihotri's Hello (2008), and Subhash Ghai's epic flop Yuvraaj (2008).

2009 began well for Katrina as her first Yash Raj Films project, New York, became the first official hit of the year. Katrina was nominated for a Filmfare Award for Best Actress.

Raj Kumar Santoshi's second foray into the comedy genre with Ajab Prem Ki Ghazab Kahani (2009) cast Katrina opposite Ranbir Kapoor. Not only was the film a hit, their screen romance spilled over into real life as well.

At the box office, the year ended on a bad note with movie number six with Akshay Kumar, De Dana Dan, flopping.

In 2010, Katrina appeared in Prakash Jha's Raajneeti opposite Ranbir Kapoor, flooring both critics and audiences alike and even winning a couple of awards.

Raajneeti's good work was undone by Farah Khan's disastrous Tees Maar Khan (2010), with fan-favourite item number Sheila Ki Jawani providing the only silver lining.

In 2011, Zindagi Na Milegi Dobara, in which she was cast opposite Hrithik Roshan, proved to be a scorcher at the box office and became one of the biggest hits of the year.

She was also seen in the candyfloss comedy Mere Brother Ki Dulhan with Imran Khan and Ali Zafar in 2011.

Katrina then sent temperatures soaring with a second item number - this time as a special appearance - called Chikni Chameli in the 2012 remake of Agneepath starring Hrithik Roshan.

Also in 2012, Katrina starred in the blockbuster Ek Tha Tiger opposite ex-beau Salman Khan. The film was directed by Kabir Khan, who previously directed Katrina in New York.

Rounding off 2012 was Katrina's role in Yash Chopra's magnum opus Jab Tak Hai Jaan, co-starring Shah Rukh Khan and Anushka Sharma.

In 2013, Katrina appeared as the beautiful circus performer Aaliya opposite Aamir Khan. The film was a blockbuster and beat all records to make over Rs 500 crores at the box office.

In 2014, she was seen in Bang Bang! opposite Hrithik Roshan. The film, a remake of 2010's Knight and Day, kept the cash registers ringing.

Off-screen, Katrina and Ranbir share an apartment in Mumbai and are now frequently spotted together at events after years of giving the press the runaround.

Katrina will next be seen opposite Saif Ali Khan in Kabir Khan's counter-terrorism drama Phantom. The film will hit the screens on August 28. In 2016, she will be seen in Fitoor, which is director Abhishek Kapoor's adaptation of Great Expectations, and Jagga Jasoos with Ranbir Kapoor. She has also reportedly been offered a role in a Jackie Chan's upcoming adventure film Kung Fu Yoga.

We wish Katrina a very happy birthday and a great year ahead.
