She was accepted after teachers at the school watched a 15-minute audition tape, submitted by a dance teacher in the UK who saw the young dancer’s potential.
Miss Millar has since moved to Russia with her mother, Lesley, and has spent her first term getting to grips with life under her new regime – not to mention navigating the icy pavements.
Mrs Millar disclosed they had been learning to communicate with the “kind and friendly” Russian via Google translate, resorting to charades in shops when necessary.
The pair have spent Christmas at the family home, and will return to brave the -16C temperatures of Moscow in the New Year.
Miss Millar, who fits in 30 hours of schooling each week alongside her rigorous ballet schedule, said: “When I first came, my teacher treated me more gently than the Russian students but now she shouts at me and I am glad because it shows I am accepted as Russian.
