That was how marriages were in the early days in America till the Hollywood marriages started signing prenups as it's called. Ciara and Russell have been dating less than a year and got engaged a month ago.
“Russell and Ciara aren’t going to have a prenup,” an insider tells HollywoodLife.com. “Even the thought of speaking such words would mean that they’re questioning their love for one another. A prenup is like a jinx. They’re not going into the marriage thinking that it won’t last. They’re diving into this full on and they don’t want bad energy clouding their marriage.” Source
