Emma Watson dazzled fans at the premiere of Harry Potter And The Deathly Hallows: Part 2 (2011) by appearing on the red carpet in a skimpy black lace minidress.

She was joined on the red carpet co-stars Daniel Radcliffe and Rupert Grint, who both wore smart suits for the launch of the first instalment of Harry Potter And The Deathly Hallows.

Watson, who stars as Hermione Grainger in the wizard series, met some of the fans who had camped out in the rain for hours in London's Leicester Square.

In the new film Watson, who plays Hermione Granger, is seen kissing Radcliffe's Harry in a hallucination sequence.

Radcliffe has said he was surprised by how passionate Watson was while filming the scene.

Watson said: "I don't know what to say. I suppose it had to be a kiss that would make Ron really jealous and so I think that's why I was so passionate."

"It was all a bit embarrassing but we just got on with it and had a big laugh about it afterwards."

She said of Daniel and Rupert: "I couldn't choose who was the better kisser. They're both like my brothers."

The film, which tells the story of Harry's final battle against the evil Lord Voldemort, will be followed next July by the concluding chapter in the saga, based on JK Rowling's bestselling books.

Emma - now a student in America and still sporting her new cropped hairstyle - teamed her Rafael Lopez dress with heels by Charlotte Olympia.

Earlier, she had talked about her sense of style. She said: "From around six or seven, my dad would let me choose what I wanted to wear, so I always had my own identity."

Rupert signed autographs for fans and said: "It's quite overwhelming but I love it."

It marks a transition from the previous films and Grint, who plays Ron Weasley, said he thought the new film would shock 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."

Actress Helena Bonham Carter - evil Bellatrix Lestrange in the film - arrived in a purple strapless gown.

Potter author JK Rowling was also there - and said the new film was her favourite of the series so far. But star Daniel - who has been playing Harry since he was just 11 - said he would have to "have words" with the multi-millionaire after she hinted there might be more books.

He joked: "I thought we had an understanding that ten years was enough."
