The media and fans speculated a long time about her participation but the French broadcaster France 3 revealed her officially in the end of January.
Her song was presented in early February and comes from her latest album Kabaret. It's been one of the favourites this year among fans and also at the betting offices.
She's been on a very successful tour introducing the album since last year. The last place she visited last weekend was the capital of Latvia, Riga (the Host City of the 2003 Eurovision Song Contest). The Latvian representative Intars Busulis himself had a concert that evening, but he still "abandoned" his audience for a moment to witness the closing songs of Patricia's concert and to bring her flowers.

Sixteen million records sold
Patricia Kaas began singing at just eight years old and has never stopped singing since. Her charm and charisma have made her one of the Top 10 French personalities for over 20 years now.
Stylistically her music is not classical chanson, but is closer to a mixture of pop music, jazz and chanson.
She has toured in more than 47 countries, performing in front of millions of people all over Europe and also as far afield as the USA, Middle East, China and all of Asia.
Since the appearance of her debut album Mademoiselle Chante… in 1988 Kaas has sold 16 million records worldwide. She had her greatest success in Germany, Switzerland, Belgium, Canada, Russia, Finland, and Korea with her third album Je Te Dis Vous. In 2002 Kaas had her film debut in And Now... Ladies And Gentlemen beside Jeremy Irons.
