Coupled Definition and 414 Threads

Coupled is an American reality show that aired on Fox from May 17 to August 2, 2016. It was hosted by television personality, Terrence J and created by Mark Burnett, of Survivor, The Apprentice, Are You Smarter Than a 5th Grader?, Shark Tank, and The Voice, as well as Ben Newmark, Dan Newmark and Larry Barron.Filming took place in Anguilla. The cast included Miss Arizona USA 2009, Alicia-Monique Blanco; Miss Colorado USA 2015, Talyah Polee; host, Domonique Price, and American singer-songwriter, TV personality, and former collegiate athlete; Alex Lagemann.
Tyler Gattuso was in the running to be a cast member on Big Brother 17, but was ultimately not chosen due to the news being leaked by online media and his Instagram hinting at the news suggesting he wasn't going to be active for quite a while. A few days later, after the cast for Big Brother was announced, he was ranting on Twitter, shortly deleting them and deactivating his account.On August 8, 2016, Fox canceled the series after one season.
