Music has defined the relationship of singer Beyoncé and rapper Jay-Z. They have songs that discuss their love and sex life as well as their marriage troubles, according to Business Insider. But one topic the two haven’t sang about is the negotiations behind their union. Beyoncé and Jay-Z supposedly signed a prenup that grants her $10 million if they divorced before two years and an additional $1 million for every year of marriage, up to 15 years, reports Business Insider. The agreement also details that Beyoncé receives $5 million for each child they have—currently, the couple has three. The nuances of their union are evident, but it makes sense, considering they have a collective net worth of more than $1 billion, according to Forbes.
