Taylor Swift will be offering live video streams of two songs she'll perform Saturday (May 21) at her Speak Now/Help Now charity concert at Nashville's Bridgestone Arena.

Originally scheduled as a dress rehearsal for the North American leg of her Speak Now World Tour, Swift decided to turn the Nashvile concert into a public event to raise money for tornado victims.

The superstar tweeted, "I'll be streaming two of the songs from the Speak Now/Help Now rehearsal performance worldwide - Saturday at 9:00 pm central on taylorswift.com."

The live stream will also include information on how to donate to the recovery efforts. One-hundred percent of the proceeds from Saturday's show will go to a designated Speak Now/Help Now fund through the Community Foundation of Middle Tennessee.

Swift says she was inspired to action after seeing so many of her band members worry over their relatives and friends who live where the tornadoes hit.

"I got the idea to open up the last dress rehearsal of our tour to the public and have the tickets benefit the tornado victims, because the day that all this was happening, we were all at rehearsal, and so many of the people on my crew have relatives in Alabama who were sending them videos of a cyclone in their local park or down the streett from them," Taylor explains. "So we turned on the TV, and we were watching coverage and it was just - it hit so close to home for us, including the tornado warnings in Nashville."

The Speak Now/Help Now dress rehearsal starts at 7:30 PM CT in Nashville's Bridgestone Arena. Tickets are still available and can be purchased here.
