Katy Perry was there for Hillary Clinton during the presidential campaign, and on Tuesday night in New York City, the politician was there for the pop star in return.
"We need champions like Katy," surprise guest Clinton said as part of the presentation of UNICEF's Audrey Hepburn Humanitarian Award to Perry, who has been an international goodwill ambassador for the children's charity since 2013.
The former presidential candidate got a sustained standing ovation at the fundraising gala when she appeared onstage, plus more cheers when she said that the "Roar" singer's lyrics "remind us when you get knocked down to get back up," the Associated Press reported.
In her acceptance speech, Perry credited Clinton with motivating her to do more than just sing.
"Hillary has lit that voice inside of me," Perry said, "and that light will never go out!"
The "California Gurls" singer attended the gala with a British guy: boyfriend Orlando Bloom, a UNICEF goodwill ambassador since 2009 and last year's Hepburn award recipient.
