Tina Turner marries her partner in Switzerland

US singer Tina Turner has married her long-term partner in Switzerland.

The 73-year-old married music producer Erwin Bach at a registry office in the Zurich suburb of Kuesnacht where they live.

It is the second marriage for Turner, who divorced Ike Turner in 1978 after suffering domestic violence.

The singer has lived with her German-born partner in Zurich for more than 20 years. She became a Swiss citizen earlier this year.

Swiss media reported they will have a Buddhist water ceremony at their lakefront home this weekend.

Newspaper Schweiz am Sonntag said David Bowie and Oprah Winfrey were among the invited guests, and the couple had written to neighbours apologising in advance for any noise.

Turner retired from performing after her last tour, which ended in 2009.
