Kirsten is a character who appeared exclusively in the 2010 stage show. She was replaced by Jade in 2011.
Her signature colour was turquoise, and her symbol was a flower.
In the stage show, Kirsten desperately wanted to break a badge-collecting record. At the end of the story, she ended up adding enough to her collection to win. When the band announced her departure, she was said to have been looking for new badges.
Kirsten sang the following songs. She also recorded the original versions of several newer songs that were not released on any albums.
