Clémence Poésy has been confirmed to reprise her role as Fleur Delacour in Deathly Hallows. Elle magazine (in France) received word that she is already back in England and will begin filming the last Harry Potter films in ten days.  Here is a very rough translation:

The young 26-year-old actress will play again “Fleur Delacour, the student branch of the School of Magic” Beaubâtons which will compete for the final tournament of sorcerers. Filming should begin in about ten days. Clémence Poésy is already at work in England.

Thanks SS!
