Dianna Agron

She’s the most famous knocked-up former cheerleader and celibacy-club president on TV. But Dianna Agron—a.k.a. Quinn Fabray, Glee’s sometimes lovable, occasionally manipulative deposed queen bee—nearly bailed on her audition for the show. “I was so nervous,” Agron admits. With her all-American beauty, Agron certainly looked the part, but the producers wondered if she appeared too innocent. “They told me to come back with straight hair and to dress sexier,” she says. “Later that week, I started work.” As the top-rated Glee wraps its first season, the 23-year-old Agron has already completed several films—including The Romantics, an indie flick starring Anna Paquin, Katie Holmes, and Candice Bergen; and Burlesque, a musical headlined by Cher and Christina Aguilera. Agron also writes screenplays; her first, the story of a 28-year-old man’s relationships with three women, is already in development. While  Agron’s scripts aren’t purely autobiographical, her experiences growing up Eloise-style in a high-end hotel—in her case, a San Francisco Hyatt where her father worked as general manager—provided her with plenty of fodder. “I got to see many walks of life—politicians, athletes, Tony Robbins,” she explains. “It was the ultimate fishbowl.”
