No white for Tina Turner, 73, on her wedding day. In a private civil ceremony, the rock star married record executive Erwin Bach, 57, after a 27-year courtship. The star-studded guest list read like an A-list yearbook. Oprah Winfrey, Gayle King, David Bowie, Giorgio Armani, and Sade, who, ironically, wore white. The festivities were held at her lakeside home outside Zurich, Switzerland.
