Of course one of Hollywood’s most notorious hotheads is the cause of this next nasty divorce. Denise Richards and Charlie Sheen looked like the perfect big name couple. However, according to Richards, their relationship started crumbling fast. “Shortly after, our marriage changed drastically. It came out of the blue, and it was more than a rough patch.” Instead of divorce, though, Richards sought a therapist. Instead of fixing her marriage, therapy brought her to the conclusion to end it with Charlie Sheen. After their contentious divorce was finalized, Charlie Sheen lashed out with public insults on social media.
