9. Robert Johnson & Sheila Crump: $400 Million
In the year 2000, the co-founders of Black Entertainment Television (BET), Robert Johnson and Sheila Crump made history when they became the first African-American billionaires ever. It was due to a multi-billion dollar deal of an estimated worth of $3 billion with Viacom. Three years later the couple made history once again when Sheila Crump walked away from their divorce settlement with an estimated worth of $400 million. They had been married for over 33 years before Crump called on her husband for having an extra-marital affair. It wasn’t all bad for Crump though, as her net worth catapulted to $670 million following the divorce.
