A newly released investigative report has revealed new details about the lives of Ivan Putin and Vladimir Putin Jr., the alleged sons of the Russian president and Alina Kabaeva, a famous gymnast who was rumored to be his long-time love interest.

Putin, now 71, had two daughters from his first marriage to Lyudmila Putina, whom he divorced in 2013.

The Kremlin has for years denied any connection between Putin and the 41-year-old Kabaeva. However, media speculation about a romantic connection between the two has been going on for more than a decade.

The investigation, first published by the Dossier Center and later redistributed to The Moscow Times, found that Putin and Kabaeva began a relationship in 2008, about four years after she won the gold medal at the Athens Olympics.

The report is intended to give readers a rare insight into Putin’s personal life, which has remained a secret for years.

In 2015, the couple reportedly welcomed their first son, Ivan, at the Sant’Anna Maternity Clinic in Lugano, Switzerland. Four years later, in 2019, their second son, Vladimir Putin Jr., was reportedly born in Moscow.

The report cites sources close to the president who claim that the Russian president himself made decisions about the place of birth of each child.

“When he was born, Vladimir Putin was so happy that he shouted: ‘Hurray! Finally! A boy!'” – claims one source published in Russian media.

The two boys are said to live in seclusion at their father’s mansion located in the Valdai National Park, a vast and remote estate northwest of Moscow.

According to the Dossier Center, their lives are filled with nannies, governesses and sports coaches.

The report noted that Ivan and Vladimir Junior rarely have contact with children their own age, spending most of their time alone or with adults appointed by Putin to supervise their development.

The investigation reveals in detail that the children see their parents only late in the evening, and meet their peers only during large, ceremonial gatherings.

According to the report, their lives, although lavish, seem surprisingly isolated from the outside world.

The family reportedly spends a lot of time at Putin’s residence near Sochi. In the summer, they go on long yacht cruises in the “safe waters” of Russia.

Putin’s residences in Crimea are also a frequent destination for family holidays.

Ivan and Vladimir Jr. are being taught by governesses and teachers hired through the English Nanny website, sources said.

One recent job advert for an English teacher promised a high salary of €7,700 (A$12,500 a month), paid accommodation and a five-day workweek.

However, the job came with harsh conditions. Leaving the family home is strictly forbidden, and candidates must undergo numerous medical tests before they are allowed to work.

In addition to English lessons, the boys reportedly attend music classes and learn German under the supervision of a Bosnian teacher, Sofija Božić, who has been working with the family since 2017.

The investigation found that teachers and coaches rarely communicate with families directly, instead reaching out through numerous assistants.

Both boys reportedly have a large Lego collection and use several iPads for games and online lessons.

The Russian leader’s “official” children

Putin has two officially recognized children – Maria (37) and Catherine (35), both from his relationship with his first wife, Lyudmila Ocheretnaya.

Doctor Maria Vorontsova, a year younger than Kabaeva, was born when the Russian president was a KGB spy in Germany.

He is an expert in the field of rare genetic diseases in children and works as a principal investigator at the National Research Center for Medical Endocrinology of the Ministry of Health of Russia.

Meanwhile, Katerina is the deputy director of the Institute for Mathematical Research of Complex Systems at Moscow State University.

She’s a former rock ‘n’ roll dancer who does high kicks.

Both daughters have been targeted by Western sanctions – unlike Kabaeva and Putin’s unrecognized “illegitimate daughter,” 19-year-old Luiza Rozova.

Luiza is the daughter of 45-year-old Svetlana Kryvonogikh, a former cleaning lady and now a multimillionaire, currently co-owner of a large Russian bank. She is one of the richest women in the country, her fortune is estimated at $130 million.

Many Russians believed Kabaeva was the reason for the breakdown of Putin’s marriage to former flight attendant Lyudmila, 63, in 2014.

Putin has previously said: “I have a private life, which I do not allow interference in. It must be respected.”

Belarusian President Alexander Lukashenko previously suggested that the reason for Putin’s divorce was that Kabaeva “was putting pressure on the president.”

Meanwhile, Kabaeva went on record as saying that she had met a man whom she “loved very much” and delightedly stated: “Sometimes you feel so happy that you are even afraid.”

Kabaeva has avoided publicity during the war in Ukraine, but her media company has openly supported the Russian president.
