3. Whitney Houston and Bobby Brown

They both met when he was a successful R&B singer and she was a chart-topping R&B singer. This could have been a match made in heaven, but instead it was the opposite. Throughout their relationship, there were reports of alcohol abuse, DUI, Bar fights, domestic abuse, drug use, arrests, and rehab stints. Despite the problems in their marriage, Whitney and Bobby stood by each other. They appeared to have a strange love for each other, as documented in their reality show "Being Bobby Brown." But soon after, the Diva filed for divorce, ending their 14 year marriage.
