"We'll just show up," the country star told PEOPLE Wednesday night after picking up top honors at the CMT Music Awards about her and hockey player fiancé Mike Fisher. "It's mainly about family and friends and the two of us. So it's going to be good no matter what."

"We need to get a running order going on. We have a dress and stuff but most of the things are like, whatever," she says.
