The former Secretary of State honored the pop star, who campaigned for her during the 2016 presidential election.
Katy Perry was really feeling the love on Tuesday night at the 12th Annual UNICEF Snowflake Ball in New York City.
The pop star -- who serves as a UNICEF Goodwill Ambassador -- was honored with the Audrey Hepburn Humanitarian Award, which was presented by none other than Hillary Clinton. The surprise introduction moved Perry to tears.
"We need champions like Katy now more than ever," Clinton -- whom Perry campaigned for during the 2016 presidential election -- said. "We need her passion, her energy, and, yes, her voice -- 'louder than a lion.' We all know Katy as a global megastar. The powerful voice who reminds us when you get knocked down, get back up."
After the heartfelt introduction, Perry took the stage to accept her award in a stunning Marchesa gown. "I’m humbled to receive the Audrey Hepburn Humanitarian Award tonight and celebrate 70 years of UNICEF’s lifesaving work for the children of the world," she said. "Audrey Hepburn remains a sparkling example in her career as well as her dedication to being a champion of children. Her life is an inspiration most of us will never match, but hopefully we can aspire to. I’m proud to carry on her shine and to use my voice to help bring attention for issues that affect the world’s most vulnerable children."
Perry's boyfriend, Orlando Bloom, also showed his support for the "Roar" singer during the auction portion of the evening. Perry donated a VIP concert experience and it was Bloom who gave the opening bid. It ultimately was sold for $50,000.
While on the blue carpet, the 32-year-old performer gushed over her guy to ET. "Everyone is a teacher in a relationship, that's how I see it now," she said. "We've taught each other a lot."

Perry and Bloom's appearance at the UNICEF ball comes after she was spotted wearing a yellow diamond on Monday night that inevitably sparked engagement rumors. She did not, however, wear the ring to the event.
