Blake Shelton is avoiding being called a "groomzilla" by leaving all of the wedding planning in Gwen Stefani's hands. He told USA Today that she is in control of every detail surrounding their big day. "I want her to do all of that stuff and handle it because it's going to be great. She's in the middle of planning the thing, and she's always so mindful of me. She's like, 'Hey, I don't want to just take this thing over.'" Blake also said that he would pick everything fried when it comes to what to serve their guests, so that's in Gwen's control as well. "I think she knows it would be a pretty classless wedding if I was in control," says Blake.
