Back in 1987, the 47 year old Tina Turner started dating a 31 year old record executive from her label. 26 years later, the couple are getting married. Next week, Tina Turner and Erwin Bach will marry in Switzerland. recently Tina became a citizen of Switzerland where she has lived since 1995. I wonder if this marriage will change anything between the pair. They have been going great for over a quarter of a century so now that they make it official, I do wonder if in the next year or two they might get divorced. I don't want that for them, but I do find it interesting they have decided to formalize everything now.
