Well here's the scoop: Hunter Hayes didn't get married this week (probably).
The rumor started with Media Mass, a website who states that it is "a humorous parody of Gossip magazines, all stories are obviously not true."
Good to know. Unfortunately, to know this about them you have to dig for that bit of helpful information. That means that when they have a story like this it always gets people worked up over something that's 100% not true and isn't meant to be taken as gossip gospel.
Would definitely help if a site who claims to be a "humorous parody of Gossip magazines" was actually funny, but that's just me.
