An outsider may look at the rough-and-rowdy Brantley Gilbert and actress and model-turned-country singer Jana Kramer and wonder why they work so well together. It sounds like they do, too. In an interview with Taste of Country, Gilbert described his relationship with his fiance with one simple phrase...

"Who knew?"

That's it. Gilbert and Kramer will get married at some point (a date is set, but he's not sharing) and then keep cheering for each other, supporting each other and competing with each other. The 'More Than Miles' singer described his fiance as his best friend, but added that things can get heated between them in more ways than one. They have a championship belt in the house to recognize the current Crazy Eights champion.

"Which I would like to make common knowledge I am the two-time reigning, defending Crazy 8s champion," Gilbert shouted before chuckling to let everyone know they don't take it that seriously.

There was much talk about the competition for the New Artist of the Year award before the ACM Awards. The prize ultimately went to Florida Georgia Line, but Gilbert said he was cheering for Kramer. He's her biggest fan.
