What is the umbrella girl's name who was in yellow in the Denmark's Speedway GP 2011?

On every speedway gp there are four girls who have umbrella and they stand in front of their racer. The girl in red stand in front of the red racer, the yellow girl in front of the yellow racer etc. I want to know what is the girl's name who was in yellow in the denish speedway gp in this year.
