Connie Talbot is over the rainbow

When I first heard it during her recent visit to Taiwan to the One Million Superstar contest on last Friday, Connie Talbot's sound is really impressive especially when I realised that she won the talent contest in UK last year when she was only 6 years old! Although she sang "Over the rainbow" everywhere but that's not all she know. She even sang a song of my favorite, "I will always love you" originally by Whitney Houston! I just couldn't imagine that she is only seven years old currently and you won't able to know just from her voice. Her voice is so big that even the Bodyguards' Kevin Costner would fall in love with her!!

Only one thing I'm just wondering why should she shaking her head repeatedly when singing a song? Is that she is nervous or can't help but trying to create a more sexy, mature way of singing?
