Eurovision Royalty: Helena Paparizou

An interesting thing might happen later this year. A former Eurovision winner is trying to return to the competition. But this time, she's aiming to represent a different country.

Eurovision Royalty: Ruslana

In 2004, Ruslana became the first Ukrainian artist to win the Eurovision Song Contest. The Ukrainians debuted at Eurovision the year before; on their second try, Ruslana was awarded 280 points by audience votes, the most in ESC history at the time.

Eurovision Royalty: Céline Dion

Well, OF COURSE Céline Dion competed in Eurovision.

Eurovision Royalty: Carola

Carola Häggkvist is a Swedish singer and performer. She competed at Eurovision three times: in 1983, finishing third; in 1991, winning the contest; and in 2006, finishing fifth. To this day, Carola is a superstar in Sweden.

Eurovision Royalty: Lys Assia

Born in Switzerland in 1924, Lys Assia was the winner of the first-ever Eurovision Song Contest, held in 1956. She began her career as a dancer, but eventually transitioned to singing.

She returned to Eurovision in 1957 and 1958 to compete again for Switzerland, and she remains an important figure in the contest to this day. Every few years, she'll come out with a new song and attempt to re-represent her homeland.

Most recently, she teamed up with hip-hop group, New Jack, and recorded "All In Your Head." Switzerland decided to pass on this entry, unfortunately. Many were hoping that this mess would make it to the finals. But she's 89 years old, so good for her anyway.
