Viewers' minds were blown when HGTV'sHouse Huntersfeatured, for the first time, a "throuple" which is a three-person relationship. In the episode were Lori and Ben, who've been married since 2002, and Angellica, who they met at a bar, after which the three fell in love. They have since made things as official as legally possible with a commitment ceremony in Aruba. They were looking for a house in Colorado that would work for them -- needing, for example, a master bathroom with three sinks -- Brian and Lori's 12-year-old and 10-year-old children. People took to social media to express the shock, and had some mixed reviews. It's the first time the show has featured a polyamorous relationship. (USA Today)
