Shania Twain is making a highly anticipated return to the CMA Music Festival, where she will be signing copies of her newly released autobiography, 'From This Moment On.' The sexy singer/author is scheduled to sign at downtown's Bridgestone Arena on Friday, June 10 from 2-4PM. Twain's appearance during the festival, held on June 9-12, marks the first time she has been back at the event in 15 years.

"I'm so thrilled to be part of the Festival," says Twain. "It is a huge reunion each year for fans and artists, and I'm looking forward to seeing some of the artists I haven't seen in awhile and connecting with the fans who have been so supportive through the years."

Twain will be sure to see many familiar faces during the four-day festival, as she recently surprised the entire studio audience during her appearance on the 'Oprah Winfrey Show' with two-day passes to the event, as well as accommodations at the Gaylord Opryland Resort.

"We are thrilled that Shania is back for the 40th anniversary and bringing another 300 fans to the party," says CMA Chief Executive Officer Steve Moore. "She is such a warm and respected ambassador for the format and her connection with her fans speaks to the heart of what makes this event such a success."

Twain last appeared at the CMA Music Festival was back in 1996, when the event was still known as Fan Fair and being held at the Tennessee State Fairgrounds. Twain's bestselling book is currently available nationwide and will also be for sale onsite at the 2011 CMA Music Festival.
