Emma Watson is Ziegfeld Zexy

Emma Watson dons a sexy (but still cute!) Proenza Schouler ensemble at the Harry Potter and the Half-Blood Prince premiere held at New York City’s Ziegfeld Theatre on Thursday (July 9).

On the red carpet, the 19-year-old British actress was sandwiched in between co-stars Daniel Radcliffe and Rupert Grint.

At Tuesday’s UK premiere, photographers caught Emma accidentally flashing her underwear while adjusting her dress.

“This was a small wardrobe malfunction, it happens,’ Emma explained to David Letterman Wednesday night. “At least I’m wearing underwear! I’m still learning, I’m still learning!”
