AceShowbiz - Relationship, how complicated it may seem, is often regarded as a bond between two individuals that requires commitment and loyalty to one partner at one time known as monogamy. Some spouses see marriage as the ultimate goal of relationship and some do not, but most relationships go through similar phases, including the development of romantic feelings, sexual intercourse and living together.

However, in modern society, some may think that monogamous relationship is too conventional and unrealistic since the notion of exclusivity may require someone to supress desire for another individual or a third person. While this kind of unconventional relationship known as polyamory or polygamy is often opted out for practical reason since it may cause commotion due to anger, jealousy and rivalry, some celebrities have proven that non-traditional relationship can work.

Some celebrity couples are open about their practice of unconventional relationships and some are not, but there are also those hiding it in plain sight. Meanwhile, a few give a tweak and twist to traditional relationship, though it is not as extreme as it may sound.

Here are ten celebrities and their partners whom you may already know or not have been practicing unconventional relationships.
