The show was held to benefit the victims and families involved in the terror attack at Grande's concert in Manchester last month that left 22 people dead and over 100 injured.

In the video, Katy is seen rehearsing for the show, greeting Coldplay's Chris Martin, Justin Bieber, Miley Cyrus and taking pics with Niall Horan. The singer also does an interview right before taking the stage.

"I'm here to give love," Perry says. "I love Ariana and all the fans of music… We're all in this together and that's why I'm here."
