DAWSON: BULLYING BEAUTY

Rosario Dawson doesn't just talk the talk; she's also perfecting the walk. "I've been taking lessons on how to be tough," the 27-year-old actress, currently shooting Quentin Tarantino's horror flick Grind House, told PEOPLE at the 10th-anniversary bash for the Lower Eastside Girls Club in New York City. "I'm working with Zoë Bell, the stuntwoman for Uma Thurman on Kill Bill, and she's pretty badass. We talk all the time about how actors in movies are supposed to be [thugs], but then they'll stand wrong. They act tough, but they don't really look it."

Sarah, Don't Quit Your Day Job

Lots of celebs have been landing roles on Broadway, but don't expect to see Sarah Chalke on the Great White Way any time soon. "One of the reasons I wanted to be an actress was because I wanted to play Eponine in Les Miserables. Then I figured out I couldn't sing," says Chalke, 30. Scrubs fans will get an earful of her vocal skills—or lack thereof—in a musical episode set to air this season. "It was fun to sing and dance after six years [on the show]. Zach [Braff] is fantastic! Donald [Faison] has an amazing singing voice. Everyone can sing [but me]. I need help!"
