Taylor Swift will give fans an early taste of her upcoming Speak Now Tour for a very good cause. The country darling announced on Friday (May 6) that she will allow fans to buy tickets to the final dress rehearsal of her tour to benefit communities devastated by tornadoes in the South in late April. According to the Associated Press, Swift has been preparing for her upcoming trek over the past five weeks at Nashville's Bridgestone Arena, which will be the site of the "Speak Now ... Help Now" benefit. Although the chart-topper is used to speaking frankly about her personal life in her music, Swift has never invited fans to check out how she gears up for her live shows. The songstress explained that witnessing the havoc-wreaking storms while putting the Speak Now Tour together inspired her to switch things up and take action. "I was watching the coverage of the tornadoes backstage at rehearsals, and I wanted to do something for the families affected by the damage," Swift told the AP. "I've never opened a rehearsal to the public before, but I felt that inviting my fans to the last rehearsal for the Speak Now Tour would be a great way to raise money." The songbird added that the benefit will be different from her other live appearances, as she is still hammering out the kinks of the production. "We will probably still be doing some fine-tuning to the show that night, since this will be a true rehearsal, but I feel like it is so important for me and my fans to help if we can," she said. Swift's Speak Now Tour is slated to kick off May 27 in Omaha, Nebraska, but before she hits the road, the Grammy-winning superstar is set to unveil her latest video, "Mean," on Friday night (May 6) on CMT and CMT.com at 10 p.m. ET.
