Shania Twain visited the 'Oprah Winfrey Show' today (May 3) to dish with the talk show queen about her new book, 'From This Moment On,' and her new reality series, 'Why Not? With Shania Twain.' Audience members expected the singer to divulge information about her new marriage and new music, but they also got an unexpected surprise.

With the announcement that she will return to the CMA Music Festival after a 15-year hiatus from the annual event, Shania offered two-day passes and accommodations at the Gaylord Opryland Resort in Nashville to every person in Oprah's studio audience. The singer will also host a private brunch for the audience members when they travel to Nashville in June.

Shania's return to the four-day music extravaganza marks her first since 1996. The country music icon is set to sign autographs for eager fans at the Nashville Convention Center.

It was announced yesterday that Taylor Swift will perform the closing set on June 12 at LP Field. The 'Mean' singer will join the Band Perry, the JaneDear girls, Miranda Lambert, Darius Rucker and Blake Shelton in the Sunday night lineup. This marks Taylor's sixth consecutive appearance at the annual country music celebration following last year's impressive 15-hour autograph singing marathon.

Fans can purchase CMA Music Festival tickets through Ticketmaster or by calling 1-800-745-3000. They are also available at www.CMAfest.com or by calling 1-800-CMA-FEST.
