"We haven't gone on our honeymoon," Owen, 30, told PEOPLE at the CMT Music Awards on Wednesday.
While the newlyweds' retreat can wait, tying the knot just couldn't.
"With this tour starting with Kenny [Chesney] and Tim [McGraw], I said, 'Babe, if we don't [get married] this year, I'm going to be busy all throughout next year,' " Owen said. "Lacey was just like, 'Let's just do it now.' "
The pair exchanged vows in an intimate and casual sunrise ceremony in Vero Beach, Fla., where they each stood barefoot in the sand.
The wedding fit perfectly with the couple's easy-going approach. "Our personalities are very laid back," Owen said on the red carpet at the CMT Awards, while Buchanan added with a smile, "We just like to have fun."
