Rosario Dawson at Whitney Contemporaries host Art Party sponsored by BCBG Max Azria. New York City, USA - 5.07.07

Dawson appeared in an episode of Ashton Kutcher's MTV practical joke show when she was lead to believe her limousine knocked down a pedestrian.

When the Sin City star bumped into the Mighty Aprhodite actress in Los Angeles International Airport, she was stunned when Sorvino referred to Punk'd instead of one of her movies.

Dawson says, "I was like, 'Thanks, Oscar-winning actress. I'm really glad that Punk'd is my most memorable work.'"
