Democratic presidential front-runner Hillary Clinton made a Katy Perry reference onstage at a rally in Iowa accompanied by Perry and her husband Bill on Saturday.

“I believe in her future, her vision. I believe in her policies. I believe in equal rights for men, women, pay,” Perry said, seeming confused about the talking point.

“You know, sometimes it’s important: you just have to Roar,” Clinton said, referring to Perry’s song “Roar,” which the entertainer performed.
