Jana Kramer's hubby-to-be, Brantley Gilbert has a new nickname: "groomzilla." "We were going to look at wedding locations," Brantley told ABC News Radio recently, "And the wedding planners, I was supposed to be following them, and they were driving, like, 30, and I just can't work with that. I was at home in Georgia, and I know all those roads and they were getting lost. Finally, I was just like, 'To hell with it.' I passed 'em, and I met 'em there. I was like, 'Y'all just meet us at the place. Y'all got GPS.'" Brantley adds that his main concern is his future bride's happiness. "I'm just picky," he explains. "I want to make sure she's happy on that day." [Quotes via Country Weekly]
