Hillary Clinton surprises Katy Perry at UNICEF gala to present award

In her second public appearance since conceding the election to Donald Trump on Nov. 9, Hillary Clinton surprised one of her biggest supporters during the campaign, Katy Perry.

Clinton presented UNICEF's Audrey Hepburn Humanitarian Award to Perry at the organization's annual Snowflake Gala on Tuesday night in New York City.

"I have seen Katy's commitment to the causes she believes in firsthand," said the former secretary of state, according to The Hollywood Reporter, of the 32-year-old singer who became a Goodwill Ambassador in 2013 for the United Nations Children's Fund. "I've gotten to spend time with her, and I know how deeply she cares about making our world a better place. She is serious about understanding the complex problems we face and pulling people together to solve them. We need champions like Katy now more than ever: her passion, her energy and, yes, her voice, louder than a lion."

Perry hugged Clinton upon taking the stage to receive the award and was brought to tears according to some in attendance. In her speech, Perry turned the attention to Clinton, whom she said "lit [a] voice inside of me, and that light will never go out. It will continue to get brighter and brighter and brighter. Thank you, Hillary. You motivate me and so many millions of people. We appreciate you, your incredible work, your heart."

Perry added: "Truly my work has just begun, and this award is a starting line, not a finish line."

The pop star has focused her efforts on "engaging young people in UNICEF's work, traveling to some of the poorest and most remote regions in Madagascar and Vietnam to bring awareness to UNICEF's child protection, education, and health programs," according to a statement announcing the award.
