Tina Turner has tied the knot with her boyfriend Erwin Bach.

A Swiss municipal official confirmed to Reuters on Wednesday (17.07.13) that the pair married ''a few days ago'' in Zurich, Switzerland, during a civil service ceremony.

The couple are allegedly planning an intimate Buddhist wedding at their home this Sunday (21.07.13) with around 120 guests to celebrate their union.

This will be followed by a star-studded white-themed party, where Tina will reportedly wear an Armani gown.

David Bowie, Sade and Oprah Winfrey are among the high-profile guests thought to be attending the event, which Tina has apparently warned neighbours about, apologising in advance for the noise levels.

Tina and Erwin, who is 16 years younger than the 'GoldenEye' vocalist, have been together for 26 years and have lived in Kuesnacht, near Zurich, for 20 years.

The couple met in Germany in 1986, when Erwin managed EMI, Tina's record label.

The 75-year-old singer was previously married to Ike Turner, who she divorced in 1976 due to his abusive behaviour. He died in 2007.
