Luke Bryan Vows to Never 'TV Cheat' on His Wife

Game of Thrones is a cultural phenomenon and nearly everyone is obsessed with finding out who will end up ruling over Westeros from the Iron Throne -- even Luke Bryan and his wife, Caroline Boyer. However, with the final season of the hit HBO fantasy drama airing on Sundays -- right at the same time Bryan serves as a judge on American Idol during their live episodes -- it's proven to be a challenge for the couple. "My wife and I -- and I'm sure a lot of couples out there do -- [we've made] it a weekly deal where you go watch it together," Bryan told ET backstage after Sunday's Idol. "But I've been out here on Sundays, so every week she's like, 'Don't you TV cheat on me!'" Bryan shared. "And I'm like, 'I would never TV cheat [on you] with Game of Thrones!"
