Jessie J, an ''olympic'' singer.

Jessie J, a 24 years actress, was the front women in the 2012 Olympics at London. She arrived on the stage singing in a car, and then she continued her show followed by the olympics viewers.
Despite the amazing impression she gave, Jessie thank (in the end of the show) all the participants for the work that they've done during the London olympics.

As I thought Jessie J is the best english singer ever. And thanks to the Music London School she became what she has became.
