Kelly Clarkson doesn't sweat the small stuff, even when it comes to prepping for one of the biggest days of her life.

Although the engaged superstar, 30, tells PEOPLE her upcoming wedding with Brandon Blackstock, 36, has been "a lot to plan," she's "not going to be a bridezilla."

In fact, she says she's "going to be the opposite," explaining, "I'm going to be like, 'Oh, the cake fell off the porch, that's fine. Cool, something's on fire, cool, whatever, we'll move it. We'll get married over there.' I'm going to be that girl."

Says Clarkson, "I never really thought I'd get married, so it's kind of cool that I fell in love and I'm getting married."
