Video of the incident shows that Shawn was mid-interview when he became distracted and looked behind him. "Someone was just touching my butt," he explained apologetically. "Sorry."

When Shawn and the two interviewers realized who it was, they all laughed. "Oh, it was Katy Perry who was touching my butt," Shawn said, putting a hand to his chest in surprise. "I should have turned around."

Shawn tried to brush it off, explaining that he was a huge fan of Katy. But he remained visibly shook, unable to resume his conversation. "Sorry, I'm just stunned," he told the interviewers a moment later. "I've never met her before."

Many fans and media outlets interpreted the moment as a joke.

But plenty of others pointed out that few people would be laughing if the roles had been reversed. If a 32-year-old man fondled the butt of an 18-year-old woman he didn't know, would anybody find her flustered response funny? Almost definitely not. They'd call the man's actions sexual assault (correctly, I should note).

I'm confused as to why people think it's ok that Katy Perry touched Shawn Mendes' butt, because that doesn't sound ok to me — mags (@frenchfriesxoxo) March 6, 2017

"What if you grabbed her butt back?" one of the interviewers jokingly suggested to Shawn.

The "Mercy" singer made it clear that he finds such behavior unacceptable. "No, I cannot do that," Shawn said. "That's not good. That's not a game."

Katy has not yet commented on the incident.
