Emma Watson Underwear Photos: Emma Watson Wardrobe Malfunction at Harry Potter London Premiere

Emma Watson attended the Harry Potter and the Half-Blood Prince Premiere held at the Odeon Leicester Square in London on July 7.

It was heavily raining. The 19-year-old actress graced the red carpet in a designer gown and transparent umbrella. But her underwear was accidentally flashing because of the strong wind.

Emma talked about her recent wardrobe malfunction on the David Letterman Show Wednesday night. "This was a small wardrobe malfunction, it happens,' Emma laughed, adding, “At least I was wearing underwear.”
