Famous non-monogamous people
The list of famous people could be almost endless so take this list only as a highlight.
We have to admit, as well, that this page is a bit gossipy - but we can't help that. We live in an age when coming out as an ethical non-monogamist can still affect your professional life, so it's easy to understand why many try to keep their life philosophy under cover.
We also list these relationships knowing that many are not good examples, best practices. The aim of this page is only to show you how much more people have lived and live now in ethical non-monogamy than many would expect.
To show you how much you are not alone!

The Marston-family
After the success of the Hollywood movie titled "Professor Marston and the Wonder Women" arguably the American academic (creator of the Wonder Woman cartoons and inventor of the lie detector) William Moulton Marston and his two partners Elizabeth Marston and Olive Byrne became the best-known polyamorous people in the world.

Will Smith & Jada Pinkett Smith
There have always been rumours about their open marriage. Sometimes they seemed to admit living in an open relationship for two decades. Jada once even explicitly said they have been in "non-sexual throuple for years" with Will's ex-wife. Jada's affair with August Alsina happened with Will's blessing. But as they didn't state the nature of their marriage officially, all this remains to be gossip.

Franklin & Eleanor Roosevelt
The 32nd president of the United States and his wife lived in a polyamorous relationship involving multiple partners including his bodyguard Earl Millerrel and the journalist Lorena "Hick" Hickok. There are many conflicting resources about their lifestyle - but what else can we expect of a time when they even had to hide that the president was tied to a wheelchair?

Angelina Jolie & Brad Pitt
The once most famous couple on Earth, "Brangelina" also admitted their open relationship. One might say they are a pretty bad example for ethical non-monogamy but it's not our duty to judge other people's lives. What seems certain is that they haven't split up because of an external relationship more possibly because of Brad's drinking problems.

Warren Buffett and his two partners
One of the most successful inventors of the history (the richest man of the world in 2008) lived in a 52-years-long marriage with Susan Thompson. But their relationship has also had a place for Astrid Menks who became part of their triad in 1977 and whom he also married after Susan passed away. They even sent postcards to their friends signed by the three of them together.
