Putin's lover loses her cool in week she is revealed to have two young sons with Kremlin dictator, as she cruelly reduces teenage gymnast to tears on video

Vladimir Putin's lover snapped with impatience at a weeping young gymnastics star in the same week she was said to have two young sons with the Kremlin dictator.

Furious Alina Kabaeva, 41, was reported this week to have two sons, aged nine and five, with the Russian ruler.

The boys allegedly live like princes, isolated in palaces with their own chauffeur-driven cars, and also travel in presidential armoured trains, planes and yachts, while annoying their father with their love of Disney characters.

But extraordinary footage from this week shows Kabaeva - an Olympic gold-medal winning rhythmic gymnast - berating talented Karolina Tarasova during a training session in Sochi, reducing the teenager to tears.

The girl, from Putin-occupied Donetsk in Ukraine, is a student at Kabaeva's elite gymnastics Sky Grace Academy in Sochi, which released the videos of the grumpy secret Kremlin first lady, who appears to be wearing a wedding ring, possibly suggesting a secret marriage to the Russian warmonger.

Karolina drops a prop in front of watching Kabaeva who rages at her: 'You have done it now on purpose, Karolina.'Do you hear me? Look at me.'Why are you doing this on purpose? You could catch the club now.'

The girl - 14 this year and with international medals in top competitions to her name - apologised to Kabeva, saying: 'Forgive me, please'.

Kabaeva responded: 'What has happened with you actually? I do not understand. What?

Karolina, after promising it wouldn't happen again said she failed 'because I [just] can't do it'.

Kabaeva told her: 'You can actually do. You know I will not cry, I will not humiliate.

'I'll just turn around and go. And this is the most awful thing - indifference. Remember it. Don't do it again Karolina, never at all.

'This is simply, you know, not to love yourself in such [a] way, to be humiliated with all other seeing, that's it. And everyone is looking at you.

'Why do you do this? I do not understand. But you are losing ground yourself.

'Let it never happen again. You promise me that?'

Karolina told her: 'All right, I won't do it again.'

In another video, when Karolina repeatedly failed with her drill, Kabaeva snapped: 'You don't know how to throw or what? Are you doing this on purpose? What were you doing just now? I don't understand what's going on.

'Come here, please. Come here to me.

'Do you even understand what's going on? What are you doing? You are driving yourself crazy, you know that?

'No one is driving yourself crazy, you are driving yourself crazy. You want to train more? But this is not training. 

'This is working out mistakes. Psychological and physical, because when you go out to the competition, you will be shaking.

'And I will tell you, well, you know, you will remember. What you did badly, and not what you did well, because you have more bad than good.'

After publicly rebuking the girl, Kabaeva is seen hugging her, telling her not to repeat her mistakes and 'go on the rampage'.

Five months earlier, Kabaeva had threatened to send Karolina home to occupied Ukraine, ranting at her: 'I'm not trying to scare you, but if you go out and perform like that one more time, I will personally pack your bags, and you'll go home.

'Do you understand me? And stop crying.'

Russian gymnastics is known for its harsh training techniques and Kabaeva herself went through tough regimes as a child on her route to Olympic glory.

Dossier Centre investigative news outlet this week reported on longstanding speculation that Kabaeva had two sons with Putin, Ivan, nine, and Vladimir (junior), five.

Astonishingly, the boys have allegedly secretly had British and New Zealand citizens as governesses, but now due to 71-year-old Putin's war, the Russian ruler recruits South African citizens to teach English to his heirs.

The children reportedly live under the permanent guard of FSO [Federal Protective Service] officers.

'The brothers have little contact with their peers and see little of their parents, but they appreciate the rare moments they manage to spend with their father,' the news channel said.

They do not attend schools and are taught in Putin's palaces like the royal children of the last Russian tsar.

This week's revelations are likely to infuriate Putin who has kept the sons hidden and even refuses to acknowledge his relationship with Olympic gold-medal winning Kabaeva, which has existed since 2008, and perhaps earlier.

Dossier Centre says it has found pictures of the boys but does not publish them for 'ethnical reasons', yet believes the lavish lifestyle of the secret children is of legitimate interest.

Ivan is Putin's first son after three daughters - Maria, 39, Katerina, 37 and Luiza, 21.

Rumours of then married Putin's love for Kabaeva first surfaced in 2008, yet the Kremlin denied them.

'I have a private life in which I do not permit interference. It must be respected,' he barked in one interview.

He deplored 'those who with their snotty noses and erotic fantasies prowl into others' lives'.

Kabeva appeared on a Russian show called One Hundred Questions for Adults when she was questioned about her private life by an audience of children.

In one clip, was asked by a young boy if she had met her 'ideal man' to which she replied giggling: 'I have.'

She was then asked who the mystery man in her life was but would only reveal 'he's a very good man, a great man' though she added: ''I love him very much.'

Kabaeva said: 'Sometimes you feel so happy that you even feel scared.'

This was after she posed almost nude for Maxim magazine and was described as 'full of sex' by a photographer.
