The legendary performer re-wrote the lyrics to her disco anthem, “I Will Survive,” changing the chorus to "You Will Survive." She even treated Inside Edition to an impromptu performance.

Gaynor is raising money for Hurricane Harvey victims through her foundation IWillSurvive.org by selling "Texas Will Survive" T-shirts for $20. All proceeds from those shirts will benefit The Salvation Army.

“Please just stay strong,” Ashanti told Inside Edition in a message to those affected by the storm.

Hurricane Harvey has displaced hundreds of thousands of people and has left at least 38 people dead, but that number is expected to rise as the waters recede.
