The 21-year-singer found filming 'Story of Us' in her native Nashville was "a little bit crazy" because she had to shelter herself from the dangerous weather conditions that were hitting the area at the time.
She told MTV News: "There were a few complications. This was actually when a bunch of tornadoes were hitting Nashville.
"We had to hide. All of us, we had to hide in a room where there were no windows, so that was a little bit crazy. [But] other than that, it was incredibly fun."
After experiencing first-hand the dangerous effects of tornadoes and seeing photographic evidence of the devastation they cause, the blonde beauty went on to perform a benefit concert at Nashville's Bridgestone Arena for around 13,000 fans to raise money for those affected by the recent natural disasters.
She said: "We were rehearsing and one of my dancers, who is from Alabama, came in and showed us a picture of a cyclone in her backyard and we were just floored.
"I just felt, if there was any way that I could help with the damage done and all the families who've lost their homes, then I had to think of one. It came to me really quickly that here we are at a rehearsal in an arena where there are empty seats. What if we filled those empty seats and gave all the proceeds to the victims of the tornadoes?"
All proceeds of the show – which came to more than $750,000 – were given to assist the area.
