Bollywood's highest-paid actress Katrina Kaif and her actor-husband Vicky Kaushal have received death threats on Instagram, prompting the celebrity couple to seek police protection.

"Based on a complaint from the two actors, an FIR has been registered at Santacruz police station in the western Indian city of Mumbai. We have also initiated a probe," a police officer told the local media.

Katrina and Vicky Kaushal tied the knot in December last year. And Katrina had shared the first pictures of her and Vicky as newlyweds on Instagram only.

"Only love and gratitude in our hearts for everything that brought us to this moment. Seeking all your love and blessings as we begin this new journey together,” Katrina wrote, sharing the photos.

Basically a model, the Hong Kong-born actress began her Bollywood career with 'Boom', an action film, in 2003 that flopped. Two years later, she earned commercial success -- thanks to the romantic comedy 'Maine Pyaar Kyun Kiya'.

What followed was a series of hits -- 'Namastey London' in 2007, 'New York' in 2009, 'Ajab Prem Ki Ghazab Kahani' in 2009, 'Raajneeti' in 2010, 'Zindagi Na Milegi Dobara' in 2011, 'Ek Tha Tiger' in 2012, 'Dhoom 3' in 2013 and 'Bang Bang!' in 2014.

Katrina's other highest-grossing Bollywood films are 'Tiger Zinda Hai' in 2017 and 'Bharat' in 2019, co-starring Salman Khan. Her last action flick was 'Sooryavanshi', co-starring Akshay Kumar and Ajay Devgan.

Born to action director Sham Kaushal and his wife Veena, Vicky ventured into Bollywood as an assistant to filmmaker Anurag Kashyap in the crime drama 'Gangs of Wasseypur' in 2012. 

His first leading role was in the independent drama 'Masaan' in 2015, but Vicky shot to limelight in 2018 with supporting roles in 'Raazi' and 'Sanju', two hits.

A year later, his lead role as a military officer in critically acclaimed action film 'Uri: The Surgical Strike', got him the National Film Award for Best Actor.
