Hand Balancing act from Cirque du Soleil's "Quidam," performed দ্বারা Olga Pikhienko. And yes, I know, she sure made one heck of an entrance, didn't she? :P
The artist is Luan Leilei (I think). In this video she is about thirteen years old (I think) and she is just SENSATIONAL! Song is Stella Errans, sung দ্বারা Erik Karol. Enjoy!
