Sandra Dee, the squeaky-clean '60s teen idol best known for playing the title role in the surfer film Gidget, died Sunday in suburban Los Angeles of complications from kidney disease. She was 63. Dee, whose wholesome image was spoofed in the Grease song "Look at Me, I'm Sandra Dee," married singer Bobby Darin when she was just 16. Their romance was the basis for Kevin Spacey's recent film Beyond the Sea, in which Kate Bosworth played Dee.
