Tina Turner is engaged to her long-time partner, music producer Erwin Bach, according to a new report.

According to Swiss publication Blick, the couple plan to wed at a ceremony at Lake Zurich with chefs Rico Zandonella and Horst Petermann from Turner's favorite restaurant, Rico's Kunststuben, catering the reception.

A rep for the 73-year-old singer said "no comment" about the report, and Turner hasn't responded to the rumors.

Turner and Bach met in 1985 while he was working at record label EMI.  They have lived together in Zurich, Switzerland, for over 15 years. In January, Turner renounced her U.S. citizenship to become a Swiss citizen.

The singer has been married once before. She wed Ike Turner in 1962 and divorced him 16 years later following years of abuse.
