Talking to Access Hollywood this week, Kasey relived the moment: “Apparently afterwards, the guy that works at the label was like, ‘No, no, no.’ He was like, ‘I can’t believe you gave him a high five. That’s just unbelievable.’”
“He’s like, ‘No, there’s a way to address the royal family, and a high-five, going up top is not the way.’”
Kasey wasn’t phased by her little royal faux pas. “I was like, ‘I didn’t know. He went in for it, so whatever,’” she said.
Harry didn’t seem too worried either, as the moment was caught on camera and he was all smiles.
Kasey found out later that she was the first person to ever high five a member of the royal family in public. “Surely someone else out there is going for a high five!” she jokingly said during an interview with BBC in March 2018.
