Country superstar Carrie Underwood is a busy girl these days with a #1 single ("Temporary Home"), her current concert tour -- AND planning a wedding to her hockey player fiancé, Mike Fisher.
"We're trying to keep it as small as we possibly can, but you know, obviously, there's certain people we have to have there," Underwood told "Extra's" AJ Calloway in an exclusive backstage chat at one of her concerts, flashing her gorgeous 5-carat yellow diamond.
What about Simon Cowell attending? "I don't know. I don't want him to judge my wedding," the singer laughed.
