Tina Turner has married Erwin Bach.

The 75-year-old singer tied the knot with the German record company executive, 57, - who she has been in a relationship with for 26 years - in a civil ceremony on the shore of Lake Zurich in Switzerland a few days ago and the couple are planning to celebrate their nuptials again at a Buddhist ceremony on Sunday (21.07.13), that will be followed by a star-studded reception at their Kusnacht home.

A source told Swiss magazine Schweiz am Sonntag, the 'Simply The Best' hitmaker, who has lived in the country for 15 years, has invited 120 guests to the white-themed party, including David Bowie, Oprah Winfrey and Sade.

Tina is expected to wear an Armani gown and guests - including designer Giorgio Armani - have been asked to wear white in keeping with the theme of the ceremony.

The singer reportedly sent out notes to her neighbours to apologise for any noise or chaos the party might cause.

The couple have been dating since 1987 and met when Erwin was working as a record producer at EMI.

Tina - who was previously married to Ike Turner who she split from in 1976 because of his abusive behaviour - applied for Swiss citizenship in January.
