Sorry, Jimmy Choo!

When Reese Witherspoon walked down the aisle to wed Jim Toth at her Ojai, Calif. ranch in March, she rocked a pair of $645 Jimmy Choo "Macy" platform sandals.

But when it was time to party, she kicked off those kicks and in favor of. . .cowboy boots?

"I changed into cowboy boots," Witherspoon, 35, says during a Thursday appearance on The Ellen DeGeneres Show. "From those awful uncomfortable shoes."

The Water for Elephants star said that the rustic bash was "small and...nice. My family, it was great -- kids, dancing!"

The Oscar winner admits to getting "nervous" about throwing the party. "I don't like having birthday parties," she explains. "I like going to parties. I just don't like it when it's about me. Which is so bizarre, but then once I'm there, I'm having the best time and I dance for four hours!"

Confirming Us Weekly's reporting, she dished on the tunes of the night. "I had a country music, bluegrass, rockabilly band, and then a DJ."

One thing she and CAA agent Toth, 40, didn't have: An official wedding song.

"[We didn't have] one song -- but tons and tons of country music," the Walk the Line actress says. "I'm a big country music fan!"
