Tina Turner, 73, marries 57-year-old Erwin Bach

Singer Tina Turner has married her long-time partner in a civil ceremony in Switzerland ahead of a Buddhist celebration at their home on the banks of Lake Zurich on Sunday.

The 73-year-old "Simply the Best" singer tied the knot with German-born record producer Erwin Bach at a registry office in the Kuesnacht suburb of Zurich where they live, a municipal official said on Wednesday.

"Turner had the civil ceremony a few days ago"
