Katy Perry Comforts Ariana Grande in a Behind-the-Scenes Look at One Love Manchester

It's been nearly three weeks since many of the world's biggest pop stars came together in support of Ariana Grande and the victims of the terrorist attack in Manchester. Now, Katy Perry has shared a behind-the-scenes look at One Love Manchester, the momentous benefit concert broadcasted live by 50 networks worldwide.

The new video offers an intimate look at both the lead-up to Perry's performance and the emotional aftermath, not to mention incredible views of her collage dress. Fans can watch as the "Roar" singer rehearses an acoustic rendition of "Part of Me" and has fun with other celebrities backstage, including a hilarious moment with Miley Cyrus, a selfie with Niall Horan, and a touching run-in with Justin Bieber who tells her, "It's awesome that you're here, doing this." Perhaps most moving, however, is the extended hug Perry shares with Grande backstage.
