Lady Gaga made a surprise appearance at a concert on Saturday to raise money for victims of devastating hurricanes in Texas, Florida, Louisiana, Puerto Rico and the U.S. Virgin Islands. The event, titled "Deep From the Heart: The One America Appeal," featured appearances by all five former living U.S. presidents, who gave Gaga a standing ovation after her breathtaking performance of the hit ballads "Yoü And I," "Million Reasons," and "The Edge of Glory."

"I just want to remind you that when some of us are on the edge, we're all on the edge," Gaga told the audience "We all sit around and we watch it on TV, and on the news and we feel on the edge with every single one of you even when even if we're not there. I hope every single person here tonight will join me in giving what they can to help these beautiful, vibrant communities recover. Please donate your time and your love. I really believe in everything that this incredible moment stands for."
