Taylor Swift is our hero!

The country songstress raised $750,000 Saturday night through a benefit concert for Alabama tornado victims, at a venue in Nashville, TN.

At $50 donation apiece, 13,000 fans got a chance to see Swift's final dress rehearsal (usually not preformed in front of an audience) for the upcoming North American leg of her Speak Now tour.

After performing her first song, Mine, Swift gushed to her fans: "Thank you so much for hanging out with us tonight. All proceeds tonight—T-shirts, merch, tickets, everything—will be going to the victims of the tornadoes. We don't have the final tally yet, but we do know, so far, that just based on tickets alone, you have raised over $750,000. So, thank you from the bottom of my heart for being with us tonight. I cannot tell you what a difference you are making to the lives of our loved ones in the Southeast."

The North American leg of Speak Now begins Friday in Omaha.
