"Like, I don't care what color the napkins are, to be honest," the bride-to-be said Thursday on the "Ellen" show.
"What I'm most excited for," Cyrus said, "is that look when, you know, who you're marrying, you see, the first time you're seeing the dress and everything that you've planned for months and months, like, coming together, and that you did it together."
Cyrus told Ellen DeGeneres she only plans to invite people to the wedding who really want to be there, the Los Angeles Times reported.
"This is the one day that it's what I choose and every detail is things that I love," Cyrus said. "And that look, I don't want people to ever forget about that."
