She rose to fame when she won ‘Nouvelle Star’ back in 2008! I must admit, I'm not surprised by this decision as I knew France were going to select someone who isn't established... She has also released two albums but failed to reach to masses with them - it seems no-one knows her in France! The French newspaper informed that ESC could be “seen as an opportunity to relaunch her career”. France3 are due to confirm this news later this week!
UPDATE - THIS HAS BEEN CONFIRMED!
Here is one of her songs... Bonne Chance France! ^^
