Harry Potter star Emma Watson turned on the magic with a barely-there dress as she bewitched fans at the world premiere of the latest Harry Potter blockbuster.
The actress donned a skimpy black lace mini-dress with a feathered skirt - showing a marked contrast to the prim and elegant outfits she has worn at the six previous Potter first nights.
Watson, 20, who stars as Hermione Grainger in the wizard series, blew kisses to fans who had camped out for hours in London's Leicester Square for the occasion.
She was joined on the red carpet on Thursday night by Harry Potter And The Deathly Hallows Part 1 co-stars Daniel Radcliffe and Rupert Grint, who both wore smart suits for the launch.
Deathly Hallows, the final Potter tale by author JK Rowling, has been split into two with the second film being screened next year.
Speaking about the film, Grint, 22, said he thought the new film would surprise fans.
He said: "I think they'll be quite shocked. A lot of characters die and it's quite scary. The whole world (of Harry Potter) is darker."
Author JK Rowling said the film was her favourite of the series so far - which has generated billions of dollars in ticket revenues around the world.
She confirmed she is considering writing more books about the wizarding world - but they will not feature Harry Potter.
She said: "If in 10 years' time I wanted to do another one I probably would. However, I said to Dan (Radcliffe) I don't think there will ever be another book with Harry as the central character. So Dan can sleep easy."
