And that's enough to give her pause.
"I don't care what color the napkins are, to be honest. I really don't care," Cyrus, 19, tells Ellen DeGeneres on The Ellen DeGeneres Show airing Thursday. "Because I didn't really realize until I got a wedding planning book what you have to decide on."
"It's a lot of weird detail," she continues. "I don't want to be doing too much and be crazy and forget about the moment of it all."
That means, for now, "I'm so focused on my record," she says. "I kind of don't want to be in between touring and trying to plan all that."
Though Miley doesn't reveal her actual wedding date, she does say that the talk show host's own 2008 wedding to actress Portia de Rossi has inspired her wedding planning.
"I was looking at photos from your wedding and I was looking at the look," Cyrus tells DeGeneres. "And that's what I'm most excited for."
She describes "the look" as when you see the person you are marrying for the first time at the wedding, "and when he first gets to see me in that dress."
As for the guest list, "It's only the people that you really want there. It's a day that you don't have to say, 'Well, I'm kind of obligated.' I don't ever feel like that. This is the one day that it's what[ever] I choose, and every detail is things that I love. ... I don't want people to ever forget about that."
