When Kivilaan joined the group , Vanilla Ninja had already been chosen to represent Switzerland at the Eurovision Song Contest 2005 . Kivilaan 's arrival jeopardised Vanilla Ninja 's participation in the Contest , as she was only 15 years old , and after the appearance of young participants such as 1986 winner Sandra Kim , the Eurovision had set an age requirement that all participants must be at least 16 . Kivilaan initially claimed to be 17 years old , but the Swiss selectors doubted this and discovered her true age . For a while it looked like the group would have to withdraw , but the fact that Kivilaan would reach her 16th birthday four months before the Contest meant that the European Broadcasting Union allowed the girls to compete
