Russian President Vladimir Putin has gathered the world's attention and horror after his country invaded Ukraine.
The devastation Putin's troops have inflicted on Ukrainian men, women and children has caused many to question how a man and father could cause such chaos.
The 69-year-old is notoriously private, keeping details about his family close to his chest, never publicly acknowledging having any children. However, it is public knowledge that he shares two daughters with his ex-wife.
There has also been public speculation that Putin shares children with his Russian Olympian mistress, who he has reportedly hidden away in Switzerland as the war continues.
He is rumoured to also share a child with secret lover Alina Kabaeva, one of the most decorated gymnasts in history, who won Olympic gold in 2004 and was dubbed 'the most flexible woman in Russia'.
Others also claim that Putin fathered a child with a former cleaner who has since turned multimillionaire as part-owner of a Russian bank.
Although not much is known about his alleged children, there is some information about the lives of his two daughters with his ex-wife Lyudmila Putina, who he separated from in 2013 after 30 years of marriage.
Maria Faassen
Maria Faassen is Putin's first child and the eldest daughter of two, aged 36.
Maria is named after Putin's mother and studied biology at St Petersburg State University.
After completing her studies, she went to medical school in Moscow and became a paediatric endocrinologist and one of Russia's top experts on dwarfism.
The now expert has publicly spoken about her research on genetic testing and combating rare genetic diseases.
Maria has one child with husband, Dutch businessman Jorrit Faassen, making Putin a grandad.
Katerina Tikhonova
Katerina Tikhonova, born Yekaterina Vladimirovna Putina, is the second child of Putin.
She dropped her surname Putina, opting instead to take on the patronymic surname of her maternal grandmother, Yekaterina Tikhonovna Shkrebneva.
Katerina was born in August 1986 and attended the same schools in East Germany and Moscow as her sister.
The 35-year-old is a director for the Institute for Mathematical Research of Complex Systems at Moscow State University and also studied at St Petersburg State University,
However, unlike her sister, Katerina is best-known for her success as a rock 'n roll dancer.
She became a member of Russia's Council for the Development of Physical Culture and Mass Sports in 2019 and has had a strong influence on the development of acrobatic rock 'n roll dancing.
For several years, Katerina served as the vice president for expansion and marketing at the World Rock and Roll Confederation (WWRC).
The danger was previously married to Kirill Shamalov, a part-owner of SIBUR Holding (a petrochemicals company) and son of the co-owner of one of the largest banks in Russia.
The couple divorced in 2018, with reports suggesting they shared almost €2 billion.
Luiza Rozova
Putin has never recognised 18-year-old Luiza Rozova, although many believe she is the president's third child.
It is thought that Putin had an affair with Krivonogikh, Luiza's mother. However, she has never commented on claims that the Russian leader fathered her child.
Suspicion has now risen that Luiza, who had 84,000 followers on Instagram, has been gagged by her alleged father after she stopped publicly posting five months ago when suspicions of Russian troop build-up on the Ukrainian border were first raised.
Some deny that Luiza is Putin's youngest child.
Other secret children include those some suspect Putin share's with Russian gymnast Alina Kabaeva.
Controversy has swirled around the president for years over the alleged relationship, as many blamed Alina for the breakup of Putin's marriage.
The pair have been pictured at countless events together, with the gymnast even being pictured pregnant in 2015, sparking rumours has a child with the Kremlin leader.
