Singer Tina Turner will reportedly marry music producer Erwin Bach July 21 at their chateau on the shore of Lake Zurich.
The 75-year-old singer has been in a relationship with Bach, 57, for the past 26 years.
The singer is expected to wear an Armani gown and the guests, including designer Giorgio Armani have been asked to wear white keeping in with the theme of the ceremony, reports femalefirst.co.uk.
The couple also intend to throw a wedding party at a later date.
The two have been dating since 1987 and Turner met Erwin when he was working as a record producer at EMI. They have been living in Zurich since 1995.
