A supercouple or super couple (also known as a power couple) is a popular or wealthy pairing that intrigues and fascinates the public in an intense or obsessive fashion. The term originated in the United States, and was coined in the early 1980s when intense public interest in fictional soap opera couple Luke Spencer and Laura Webber, from General Hospital, made the pair a popular culture phenomenon.
The term supercouple typically refers to fictional couples from television dramas and film, such as Gone with the Winds Rhett Butler and Scarlett O'Hara. With regard to real-life pairings, tabloids and the mainstream media have focused on wealthy or popular celebrity couples, and have titled them supercouples or power couples. Examples are the former pairing of Ben Affleck and Jennifer Lopez (which became known by the portmanteau "Bennifer"), and the relationship of Brad Pitt and Angelina Jolie ("Brangelina").
